It's an opinion and also a Fact
ps3 is better than xbox = Opinion
ps3 is better(more powerful) then xbox = Fact
I hate to be spell check pest but.
Also, Cloak is right, PS3 being better than the Xbox is mostly a matter of opinion, but that's like saying the 12 year old is better than you, and your 40, and have been playing games sense Pac-Man.
Yes the PS3 is new, and has new hard wear, thus being more powerful, you still have to remember that the Xbox 360 has been around much longer, so game Deves have a easier time coding for it, cause they know the limits of the xbox, and it's coding. Most people who go around tooting Sony's horn are Sony/PS Fanboys, or really hate the xbox and the PC or just hate M$ in general.

As you can tell by the pic, both the Xbox 360 and the PS3 are pistols, they're both user friendly, blah blah, the only difference is the age, I know it's kind of a weird image, but the joke was the PC beats all, and the Mac is a woman's toy.
Please ignore the Cockatiel in the box, I censored the image.
