It's plenty good - so far as I know, it's not super susceptible to needing to be restarted. Most residential connections won't use anywhere near the 2Gbps throughput on that one, so if your connection is more like 300 or 500Mbps, you could save a few bucks and get a lesser version. There's also a good chance you don't need 4 ethernet ports coming out the back of it, today we use three portsbut they're not adding much cost, I wouldn't think.
Once you reach a certain level of quality, the modem is rarely what causes issues on a residential network, and this is certainly above that threshold.
Do you have a modem/router combo from Comcast now? Yes.Or is this to replace a modem only (and you're keeping your existing router)?I recently purchased a Linksys AX6000 router. Most of the time I now have around 240Mbps WiFi in most areas we used mobile devices and 1/2 to 1/3 that outside. But, before we had to constantly switch which WiFi router we used and now we can just stick with one. We do have a 1GB option from Xfinity for more $$$ but don't have that.
Disclaimer: I don't know how Comcast does the voice or if you need that at all. I'll assume it's compatible with whatever services you have.
