The Giant Bomb crew, plain and simple.
The honesty. The fact that these dudes just tell it like it is, and don't seem 'bought'. That refreshing change of pace is what drew me here initially, and it's what keeps me a fan. No (or at least, very little) bullshit on this site; just the truth, and I really appreciate that.
Easily the best part of Giant Bomb: http://www.giantbomb.com/forums/off-topic-31/latest-ppv-and-weekly-show-discussion-thread-524133
It feels like these guys are doing what they're doing because they want to, not because they're paid to. That shows through in all their content, and it's what makes it so much more enjoyable than other outlets (though Greg Miller at IGN is trying his damndest to bring that attitude back to their site).
I prefer Ryan's.
The Crew, with Vinny as the most shining example. I guess the community could be nice too, but having spent time here since 2010, without ever really taking part in much about anything that has happened on the forums, I feel like I won't be giving that a try anymore.
I like the intimacy. Feels like I'm sitting on a rug palette by a crackling fire, sipping wine and sharing in camaraderie with great friends.
Not really, I mostly like the fact that the community is generally more informed and articulate than other sites, gaming or otherwise. I have better discussions about politics on here than I do on other sites dedicated to such things.
Of course, it has to be the crew/quicklooks/their awesome livestreams. Although, I think another main reason is how mature the community is. I've spent a lot more time then I should have at Facepunch. It was quite dreadful... it was just teenagers with overly biased opinions 24/7.
The rampant, gratuitous nudity.
Serious answer: everything. There are no winners or losers here. Everybody gets a trophy! Like t-ball.
Hey guys, during the beta you could use keys to post your comments, what were they? I can't remember. It was spacebar something, wasn't it? Or was it tab something?
edit: Tab space! That's what it was!
