PS3, more future proof. Games cost but its worth it (in my vision). PS3 all the way, xbox isnt that bad tho but PS3 is better - when following the facts
Yes, I post PS3 spam, but as much as I can, I still try and remain faithful to PC gaming, but sometimes it's too difficult. Hence why I play most of my games on the PS3, as it's easier, more comfortable, and only costs me the game (60$ or so), not a bunch of money to upgrade and such.
I was considering getting a 360 but decided to be patient and wait for the PS3. I do not regret my decision one bit but that does not mean to say I think that the 360 is not as good. I think they're pretty evenly matched, at the moment anyway. All down to preference and opinion etc. PC comes above all anyway!
I voted 360. Why? Consoles come down to, in my opinion, the games. Which consoles have the most games on you want. When I bought my 360 it won due to Halo 3 and FM3 and continued with FM3. Though, now considering getting a PS3 too due (though waiting for a full and final verdict of GT5)
At the moment I'm more biased towards PS3 since the 360 seems to really be losing its "exclusive" titles that are ported to PC (which is the superior gaming platform) one after another. PS3 however is just more PC-like to me with its better and more open controller support, if only 360 supported a G25, my preference might be other way around.
Only games that have gotten me to turn on my 360 lately have been the fantastic GTA4 addons. I don't think anyone can claim 360 to be a better console by hardware or design, but it does have more and better games than PS3 does.
PS3 = Better console in design & hardware. Not many interesting games.
360 = More interesting games, though many losing "exclusive" title after a year.
