To be honest I never owned a playstation or xbox console...i was always a fan of nintendo...gameboy...sne s etc... AND their games...sequels etc, i grew up with them..
I dont know Wii seems childish so im beetween PS3 and Xbox360. the 2nd is cheaper...games, well as far as i know they have the same titles..
Im thinking of PS3 maybe because came out later (I think) than Xbox so it must be better. ()
The Wii is for kids, leave it be.
My answer will generally lean to the 360, since I feel they just did such a better job this time around, and I LOVED my PS2.
As ND pointed out, you're going to see a lot of similarities in each system. Advantages of the PS3 are going to be the blu-ray player, and it seems to be superior in terms of certain multimedia streaming capabilities, but both systems are always adding features in this regard. Advantages to the 360 are going to be the online game play, and online content.
Games are subjective, but a lot of these games are developed for the 360 then ported to the PS3, so the quality suffers a bit.
Move is a joke, and Kinnect will destroy it. Check out youtube vids of Child of Eden. Developers have had time to play with the Kinnect and will be releasing some great stuff.
Online is no contest at all, XBox Live! dominates in this regard. Take CoD MW2 for example - tons of glitches on the PS3 network, and hackers have destroyed the game. There are numerous examples of this, with Sony users often getting downloadable content after the 360 users have been playing for months.
As for the controller debate, that's subjective. But, I would suggest you pick up both and see which one is easier to switch from the triggers to the bumper button. Also, the 360s thumbsticks are offset, which is more natural, rather than the linear ones Sony uses.
But, the truth in the matter is, you'll probably love either one if you buy it.
