I have Sonic at home, despite that it is basically AT&T dual bonded DSL and slower then my old Comcast connection. Its fast enough and I really like Sonic. Comcast, not so much.
What's the reason to not like Comcast? For me it was Sonic at $90/mo for 3 maybe 4mbps (not a lie), or Comcast at $80 for 300mbps. It's a no-brainer there.
I'm not doing anything illegal so I don't care about Comcast cracking down on torrents. The data caps are high enough that I can't hit them in my max-2 simultaneous Netflix streams. Comcast let me buy my own modem instead of using theirs. The only time I lost Comcast service was when all of San Francisco lost power.
Comcast is pretty bad/predatory as a cable TV operator. But we're talking about Internet service, and they're pretty straightforward there.
If you're in SF, can't get Sonic fiber, and really hate Comcast, then you should look into Monkeybrains.
I pretty much agree with all your points. So given Comcast's track record, I've decided to not give them anything I don't have to. I have no reason to believe they will treat their internet customers any better then their cable subscribers. I like the way Sonic does business, so I'm going to support them, even if its slower. Its fast enough for my purposes (and we cord-cut, game, etc)
It depends on your building's setup. We have a gig radio on the roof with G.Fast inside the building to each unit. I get 200mbps up and down. $35/mo tough to beat unless you can get Sonic fiber.
