As with most things, it depends what you want to spend, it depends on what you want it to do.
We didn't need a mesh system, so we get by very nicely with this one;
The TP Link AC1750 is a very basic, but very solid dual band switch / router that covers the end of the house I care about very well. Solid connections out in the gazebo, too. I work wirelessly a room away, running conference calls and Skype multimedia sessions without any issues. Honestly, I haven't looked at switch / routers in a while, because I have no need; this one works great. Can't beat it for the price, IMHO.
We're still running the Comtrash modem, as we have the home phone service and we can't seem to decide on it's importance. Funny thing, our overall bill is cheaper with the home phone service ("Triple Play") than it would be if I shut off the phone service. Talked to one of the honest Comcast folks on the phone and they told me that LOTS of customers pay for the phone service to get the deal on TV channels and internet bandwidth....and never use it. That's another thread.....
But - I did pick up a TP Link modem for my son that lives locally and has Comcast internet service....and it works great. Has for a while now. Easy to recommend, not sure what spending a ton more gets you other than more speed....if your provider offers it:
Amazon.com: TP-Link TC-W7960 DOCSIS3.0 300Mbps Wireless WiFi Cable Modem Router for Comcast XFINITY, Time Warner Cable, Cox Communications, Charter, Spectrum: Computers & Accessories
smile.amazon.com
That modem will run up to 300 Mbps, which covers my son's needs fine. He's a pretty avid gamer, and it has worked perfectly for his needs.
If you need voice and DOCSIS 3.1 capability (32X8 channel bonding, up to 2Gbps down), this is the one I've been thinking about;
Good luck - B.B.S.
