Meh, I feel like each has something the other needs desperately.
The 360 has WAY too much hype, which pays off when it comes to the online community. Too bad that most of them aren't too "nice". It could use better exclusives and tech capabilities, though.
The PS3 has superior capabilities, and the community on there is pretty good. It's a bit small, but PSHome is a good way to meet a lot of people.
And The Wii? No one actually likes it for serious games...
And where's the PC? It's like those guys never get the credit they deserve...
