I have FIOS and live in a fairly well connected area, so I voted for decent speed and reliable. With that said, in the past half year I've had at least two periods where there were outages lasting a couple days or more, so even with a reliable "always on" connection I've had issues.
Good speed and usually pretty reliable, but on busy days it might drop for 20-30 seconds once or twice a day (sometimes long enough to disconnect me from XBL, sometimes not). Usually not a big deal, but it's just enough to make me nervous about any service that'll kick me out of a game if I lose my connection briefly.
I have shitty DSL and I despise it with a passion. It's fine for gaming as I get around 50-80 ping but for downloading or streaming, it's pretty slow. I've also been having a lot of trouble with it recently. Hopefully I'll have better internet by the time next gen comes around. Time is ticking, though...
At my parents' house, where I lived last year, it was incredibly slow and incredibly unreliable -- it was also the only Internet solution where they live.
Now that I've moved closer to civilization, I have decent and reliable Internet for a fairly inexpensive rate. But the wounds of the slow Internet are still fresh enough that I shake my head at anybody who claims that digital-only is absolutely the way for games to go. Downloading even smaller XBLA games could take hours, and I was never able to play much Diablo III because I always got disconnected. That's an Internet reality for more people than you might think.
100mbs down (that actually hits around 150-160 when the line is empty)/ 20mbs up (seems to hit around 50-60 when the line is empty) and rock solid connection. In the year the I have had it it has gone out once when a large cyclone cause a few billion dollars worth of damage, and they had it back up in two days. I'm lucky cause all the cable from my house to the node are all new so everything is running at 100%. This should keep me going in comfort until the government come around in 8 or so years with their wonderful fiber to house and the gb/s that entails.
I've had a perfect connection for over three years. But I refuse to buy a always connected system on principal.its sets a terrible precedent. What if money gets tight and I have to get rid of my Internet? My Xbone and all the games I have for suddenly become bricks. I recently took my 360 with me on vacation so the family could play some rock band and system link halo. There wasn't internet for miles.
What happens in 20 years when I want to play grand theft auto 6? I won't be able to connect to the servers to authenticate it. WON'T SOMBODY PLEASE THINK OF THE CHILDREN?
I guess I'll just hope ps4 doesn't do the same or I guess I'll just become a Nintendo fanboy and retro gamer. I hope Microsoft burns to the ground.
Download speed is pretty good. I get a consistent ~30Mbps. Upload is terrible though at only ~4Mbps. Online verifications won't affect me in the slightest, but I still think they're bullshit as they can only prevent me from playing content that I bought while offering nothing in return.
