which gaming console is better?

Of course, "Better" is subjective, and thus it'd be better to talk in terms of:

--> Graphics

--> Online and offline features

--> Hardware

--> Kinect Vs. Move

Please suggest!!!

Xbox is better console for games.

Play Station 3 is best because i am playing game in PS3.

I'd say kinect is better.
Move's controllers look like female sex toy vibrators.

Xbox has better Multi-player than PS3 but PS3 has better graphics, hardware, and their multi-player is free while you have to pay a monthly subscription (which is steadily decreasing) for Xbox 360's live, so you get what you pay for. I personally bought the PS3 just for the blu-ray disc player. Because of the Sony hacking fiasco expect them to throw in a lot of freebies your way if you do decide to buy a PS3 and a Move since they are losing a ton of business. Gaming customers are merciless when it comes to video-gaming experience - they don't give any companies a second chance.

I'd recommend waiting a bit before buying either because after Nintendo releases their new console the prices of Xbox 360 and PS3 consoles will plummet.

who makes the best gaming computers? im tired of playing ps3 all the time

If I am being honest, I think PC is the best gaming console as well as everything else, sure not as many people play it, but there is steam which have over 9 million players, and with price you can spend £700 on a decent system at it will last longer than your average console and you will probably use the computer a lot more as well.
