Why a modem that is nearly $100 more than one that seems equivalent?
I have to buy a new modem since my old one is dying. I have found three that are approved for my ISP/plan, one of them being Netgear CM2000. I have an Orbi RBR50 system that works great so the Netgear...

not sure what the other 2 are so its tough to compare.
The CM2000 has a 2.5g port so you can connect a 2.5gig device to it for >1gig service. The RBR50 only supports up to gigabit speeds as it only has 10/100/1000mbps wan port.
So if you plan on upgrading to >1gig speeds (and upgrading routers), the cm2000 is the way to go. If you're not planning on upgrading past gigabit for the future (expected life span of modem/router) then something like the cm1000 or cm1100 would be able to saturate your router.

The two other modems are the the ARRIS Surfboard S33 and Motorola MB8611. Looks like the CM2000 has dropped in price since yesterday so now the difference is "only" $50. They all have the same spec it seems. Probably the same chip although I can't find what's in the Netgear CM2000. I do not have any voice or TV services, only Internet.
I have an Orbi RBR50 router with one satellite. I'm really happy with that and it works very well.
According to Xfinity my plan is 1.2 Gbps down / 40 Gbps up and all three modems are listed as approved and compatible with my service. My dying modem is not.

I've heard good things about the S33 but I haven't really heard anything on the MB8611
