Well I love XBOX live because a lot of my school friends are there. I like PSN because a lot of online friends are there. I like both the 360 and PS3. It's really really dumb to argue about the two, because all in all there are only benefits to a game being released on more than one console. It opens up to more audiences, catches more interest, can be more affordable to a person that wants it, and also gets the company more money. There's nothing wrong with it.
You don't have to like that console though. I for one am not a fan of the Wii at all but I'm still happy that Resident Evil 4 was ported to it a few years back because that meant people I knew who didn't have a ps2 or GC could play it, and they could play it with new features. It's how stuff grows. That's how I feel, anyway. Just play it on the console you like, and, well, love... and... peace! :D
