PS3 is easily the best console out there IMO. Pretty much is everything the Xbox is except you don't have to pay $60 a year for online play and you have Blu Ray capabilities.

That being said if you're a huge halo fiend like I am you'll unfortunately get sucked into getting the xbox.

Over the past year though I've had both and if I only had to pick one console, halo aside...my answer would easily be the PS3.
