Cox provides a great customer experience and reliable speeds, but you’ll spend more for higher-speed plans, extra data, and add-ons.
If you can get fiber internet from Optimum , you'll get great all-around service with fast speeds and reasonable pricing. If you can get only cable internet, you'll get slower max speeds and may see different pricing. Both options are decent, but watch out for third-year price hikes and potential customer service hassles.
Xfinity is a fantastic provider overall. It offers fast speeds, reliable service, and reasonable prices. Some plans still require contracts, and others still have data limits. Watch out for Xfinity’s hidden fees and spotty customer service record, but it may not be as bad as it once was.
Cox plans range from around $0.60/Mbps for low-speed plans to around $0.10/Mbps for the fastest plan, which is more expensive than other cable internet providers. The good news? Cox has more lower-speed plan options, so if your internet budget tops out at $50 a month, Cox might be your new best friend. At speeds of 200 Mbps and above, however, Cox loses the price war.
What you get for the money is pretty good. All plans have a 1.25 TB data cap (unless you pay an extra $50 per month for unlimited), but that’s more than most people need. And unlike providers where unlimited comes standard, Cox won’t throttle your speed if you get a little data-hungry. Just beware of overage charges (which can really add up) if you go over the limit.
Optimum offers a lot for the money. Both fiber and cable internet plans start at 300–500 Mbps, with a very competitive price that beats the entry-level plan for competitor Spectrum and is way less than national benchmarks (1). That's plenty fast for most online gaming and work from home needs, but you can pay for even higher speeds if you have a big household.
Compared to the competition, the two lower-tier plans almost always offer more speed for the money. And while you can technically find cheaper gig plans, Optimum still tends to be the most affordable in its markets.
If you qualify only for cable internet with Optimum, your speeds will be slower but you'll pay about the same every month. Prices are higher than other cable internet providers at these speeds, but you may not have a choice. Most areas that don't have fiber internet won't have multiple cable internet options.
We love the low starting prices, 2-year price lock, and 60-day money back guarantee, but you can expect prices to jump $35–$85 in your third year of service.
Xfinity is generally a very good value, especially at the middle and lower tiers. In fact, it offers some of the best budget plans of any of the major internet service providers, with a 50 Mbps Internet Essentials plan for less than $20 per month and a 400 Mbps plan for $50 per month in some areas. Those plans have a data cap of 1.2 terabytes per month, which is disappointing but common among cable internet service providers (ISPs). Removing it costs an extra $30.
The 400 Mbps plan, which is about right for an average family, is also a great price. It rings in at about 36% of the national benchmark in its range. (1) That means you're paying just $0.18 per megabit, with plenty of megabits to go around.
Faster plans are available, but they are pretty pricey compared to the best fiber internet competitors we reviewed. Some areas can get speeds up to 2 Gbps, and others can get plans as fast as 6 Gbps. That is ludicrously fast, but it’s also really expensive. Most households don’t need those internet speeds unless they’re streaming a ton of 4K content at the same time or have 10 or more users, so we don’t recommend them for most households. They do come with unlimited data, though, so might still be worth it for some households.
Generally, Cox delivers the speeds it says it does, sometimes even a bit higher—though the speed you experience also depends on lots of factors, such as the equipment you’re using and your distance from the router.
Cox specializes in cable internet, which is faster than DSL and satellite, but slower and less reliable than fiber. It’s also typically cheaper and more reliable than wireless internet. The US Federal Communication Commission, in fact, says actual speeds from Cox are faster than advertised and nearly identical to competitor Optimum. Those speeds are stable, too. The report found slowdowns less than 5% of the time. (1) However, cable internet is known to be slower during peak usage times because you and your neighbors are all using the same street lines.
Optimum performance is solid. With speeds up to 2 Gbps (12000 Mbps) in some states, there’s enough bandwidth available for even the heaviest of streaming households. Even the lowest-tier plans offer plenty of speed for most use cases. The cable service is generally very reliable, as well, and usually even faster than advertised, with better latency than any cable competitor. (2)
Additionally, Optimum offers fiber internet service in some of its coverage areas, which offers extra reliability and symmetrical speeds. That’s an excellent feature for content creators and anyone who shares a lot of large media files. Recently, it started offering home internet plans up to 5 Gbps, a speed that’s nearly impossible to beat.
Xfinity internet performance is excellent. Its speeds are fast and reliable. In fact, in many markets, it has one of the fastest internet speeds around. The service is reliable and consistent. If outages occur, Xfinity is responsive and generally restores service within hours. Xfinity internet is also highly rated for speed (2), and research from the US Federal Communication Commission (FCC) scored it among the top for reliability (3).
Cox’s Panoramic Wi-Fi Gateway ($13/month to rent) is a modem and router in one, and you can purchase (but not rent) additional Wi-Fi pods ($129.99 each) that plug into a regular power outlet to reduce dead spots in your home. Because these pods can be used only with Cox, they're only an ideal solution if you plan to be with Cox for several years. The good news is Cox is also compatible with tons of other modems and routers, so you could save a few bucks while using your own gear.
With Cox, a self-installation kit is free. But if getting set up on your own makes you sweat, a Cox professional can install it for $100... but that installation cost goes up if your home isn’t already wired up and ready to go. They’ll ensure cabling makes it from the street into your home, but you might need to hire a contractor or handyman to run wires to a specific room.
Optimum offers a fairly standard wireless gateway with both its fiber and cable plans. The combined modem and router are usually free, but may cost you $10 per month on top of your bill in some areas. You can also add Wi-Fi extenders for $3 each per month, which is handy for larger homes and offices (and not a bad price, either).
If you want to use your own equipment instead of Optimum's free gear, you may run into difficulties. Optimum doesn't list compatible equipment and requires at least some third-party modems to be purchased from its stores.
With Optimum installation, you can do it yourself or have a pro help, and either way is free. If you order online, you can opt for a free standard professional installation or pay $59 for a premium installation, where the tech will configure Wi-Fi on up to six devices for you. While other providers may offer to set up your main device during installation, we haven’t seen such an extensive guarantee elsewhere. This could be a selling point for less tech-savvy customers.
Xfinity internet offers the usual choice of professional and self-installation. The professional option is often more affordable than competitors, at $100. It's required if you haven't had Xfinity service at the address for more than 12 months. The self-install kit is free, though you may pay for shipping and handling. If you have trouble installing yourself, you can contact customer service for help but may face long hold times.
As for equipment, the Xfinity xFi gateway is fairly typical (and costs a fairly typical $14 per month). You can also add a Wi-Fi extender (and unlimited data) if you bump up to xFi Complete for about $15 per month for the first two years (and $25 per month starting in year 3). This is a bit steep for just the extender—you can grab an excellent Wi-Fi extender for right around $50. However, using Xfinity's equipment gives you unlimited data, and you qualify for a free upgrade after three years.

If you use your own equipment, unlimited data costs an extra $30 per month for lower tier plans, but is included for plans of at least 1 Gbps.
Reviews for internet service providers are notoriously low in general, but Cox does pretty well according to our real customer reviews. The American Customer Satisfaction Index (ASCI) ranks Cox ninth in customer satisfaction among internet service providers—the same as Frontier. (2) That's lower than average, but not by much.
We think Cox’s 30-day, no hassle money-back guarantee is solid. And in our own experience with Cox, we've had solid customer service interactions. If you opt for self-installation, you can still get plenty of help online or by phone if needed. But if you use your own gear or technology isn’t your thing, $10/month will get you extra help, day or night, for things like malware removal, software installation and reconfiguration, and general troubleshooting.
Optimum provides a good customer experience overall. Both types—cable and fiber—are fast and stable, and we haven’t seen any major complaints about reliability. We think the day-to-day experience with Optimum is fine.
However, the company’s customer service is less than stellar, with one of the lowest ratings of all providers, according to the American Customer Satisfaction Index (ACSI) (3). Most of the complaints we’ve seen involve a poor experience dealing with customer service reps. Optimum does offer solid online support options, so you may be able to get around these issues. And, of course, not everyone has a poor experience.
The Xfinity internet customer experience is kind of a mixed bag. On the one hand, you have reliable service, with the option for unlimited data if you want it. This makes for a great day-to-day experience.
On the other hand, Xfinity internet has a spotty customer service track record. Technically, it ranks above average on customer surveys (4). That said, we all remember the memes from a few years ago. While customer service seems to be improving (based on survey scores, at least), not everyone has a great experience, and we still see a lot of complaints about billing issues and miscommunication between the company and the techs it hires.
If you need to connect with the company, we recommend using its customer service portal and downloading the Xfinity app first before trying to reach reps by phone.
