reasons xbox is better:
1. More (and better) games
2. It's microsoft, so obviously tweaking them is pretty easy, drive flashing, cloning drives if one breaks, etc.
3. £4/month GOLD fee pays for better server maintenance and service, and makes up for the XBOX being, on average, half the price of the PS3. Gotta make your money somewhere.
4. Gears of War 3. Nuff said.
Plus, if they break, someone like me or my mate with a heatgun can patch it up and have it from RROD to cool 'n' running in under an hour, and i can guarantee this refurb would get a 'dead' xbox running for atleast a year if it'd done right.
although with the new slimline xboxes, failures aren't really a problem anymore anyway.
