Definitely YES! The PS3 is the superior system for multiple reasons.
1. Better graphics, faster framerate
2. It is cheaper in the long run because of free online play
3. Again, free online
4. A controller layout that MAKES SENSE. Why is the left analog stick there? I am not holding a controller like that, it is NOT a Rubiks cube!
5. Each developer makes it's own own online format, allowing for more diversity
6. The PS3 is a completely new system, not a repackaged version of the old, just with extra power.
7. Trophy sounds cooler than achievement
8. Uncharted
9. I am using my PS3 to type this post.
Ok, I think my pro-Sony rant is over now, I am just sick of X-Box players saying that their system is better with no reasons why. Ok, now i'm done.
