If a DOCSIS 3.0 modem still can't be saturated by the tier of internet someone is paying for, what advantage would 3.1 have?
If your provider has implemented it (Comcast is the only one i know of in north america) then Active Queue Management is a huge quality of life improvement that you won't know you were missing unless you already had a router that implements queue management. https://www.cablelabs.com/blog/how-docsis-3-1-reduces-latency-with-active-queue-management
Not buying another modem when the ISP quietly upgrades the CMTS and makes more speed available in your neighborhood.
Yeah I recently switched from cable to fiber (finally available), and prior I was using an old as fuck modem/router that capped at 500Mbps. My internet at fastest was 380. I rarely transfer files over the network, so figured why bother? (I did have Gen1 Google Mesh though to cover dead spots). I had a bit of a shopping splurge when I got fiber. Nothing crazy, just an upgraded mesh and a switch (Why the fuck does Frontier provide an ONT with 8 ethernet ports but only one is active?)
At least in my case, my DOC IS 3.0 modem was having connectivity issues. My neighbor in another apartment had similar issues: dropped connections, slower than expected speeds, etc. Switching to DOCSIS 3.0 modems solved the problem. I guess Comcast upgraded their hardware and it wasn't compatible with my modem anymore
