360 is the best.
PS3 is a very good alternative, but 360 is just better.
The aesthetics are better (comfortable controllers, better joystick layouts, loveier menu).
Honestly, the only things that are better about the PS3 is that:
- Has an internet browser (but it's a piece of steaming stuff, and that's what you have a computer for, durr)
- Blu-ray (okay this is a strong point, I admit, but you can still get a bluray player)
Also, the 360 is cheaper (yeah, because the internet costs money, but still, it's way less).
Lolno, you forgot that the 360 has Netflix.
OH AND YEAH
The motion stuff, forgot about that.
The Move is a Wii remote with a ping pong ball on the end lol. It's not that great. The Wii has better sensitivity. I'm not saying the Move sucks, but it could be better.
The Kinect, however, is REALLY fun due to the fact that you don't need a controller - just your body. There are times when it doesn't pick your movements up as well as it should, but it's still very fun to play with.
