My question is actually in two parts. And what I mean by "best online poker room," I'm asking about what is the best overall and which has the most credibility.

1) From what I've read, PokerStars is the best, with Full Tilt coming in second.

2) Is it worth playing online at all, considering the fact that a lot of people play using bots and other programs to give them a stronger advantage?

The biggest concern I have about playing online is whether or not it will help improve my game, considering you obviously can't see the players faces or study their body language. I've been doing very well at poker rooms in Vegas this past year, but I don't live there and I'm not ready to quit my job and go professional until I at least make it to the final round of a major tournament. But it would be nice to be able to practice with other serious players when not in Vegas.

I've been a bit technophobic when it comes to this sort of thing, but if it really does help improve one's game and strategy at brick-and-mortar tournaments, I suppose it's worth a shot.
