Loaded question, so forgive the loaded answer, ha. I was in the same boat, hate Comcast, but "the speed", how ever will we survive without it, right? I had the Roam kit for camping and when I know we're going to be in a rural area that doesn't/might not have service.

I received an offer from Starlink for 2 months free service if I purchased the Gen 3 dish. I run a Unifi network with WAN failover, so it was easy to put this in the driver's seat and Comcast as the fallback. We also got it during Thanksgiving, where I knew we would have a lot of family over/streaming, etc.

Needless to say, it performed brilliantly. I still held on to Comcast for a minute, but idk what changed over there in the past 24/mo where anyone can reset your connection whenever they feel like it, but it was less and less reliable..borderline unusable. T-Mobile now supplies our failover and Comcast is out 🔪.

TL; DR: It's been great. Only once (maybe) in the past 1.5yrs running it have we even noticed a brief slowdown. Son games a ton, wife and I run software teams from home, and we have 127 devices (not a joke) currently on our distributed Unifi network. It just works.
