I've been through 3 xboxs due to the infamous RROD and refuse to buy another one Microsoft pushed me to PS3 and I am glad they did one of the best consoles I've owned so far
---smurf-poop---. The PS3 is a $400 suckfest. Yes I have one. I play my Saturn and DreamCast more then the PS3.
I have a PS3, and it is in no way a suckfest

While the XBOX 360 might have some more exclusive games, why would you support a company that puts out such a poor product. No trolling or anything, it is a fact that Xbox 360 hardware is not reliable (RROD)
I think the following are worth owning a PS3 for:
Little Big Planet
Virtua Fighter 5
Soul Calibur 4
Mortal Kombat vs. DC
Ninja Gaiden
Motorstorm
Full Auto 2
Ratchet and Clank: Tools of Destruction
The Bigs
NCAA College Football 09
All Pro Football 2K9
NHL 09
Super Street Fighter HD Remix
Tekken 5: Dark Resurrection
Super Stardust HD
Commando 3
Everyday Shooter
1942: Joint Strike
Bionic Commando: Rearmed
Lumines: Supernova
Street Fighter IV (coming soon) + Tournament edition Fightstick
Tekken 6 (coming soon)
Dragon's Lair (Blu Ray)
Space Ace (Blu Ray)
And many other games that arcade fans would agree are great!
