I've never owned a PS1/2/3, that being said, I love the X-Box, and the 360. I think they're both great consoles, run smoothly, good games, Microsoft's warranties are boss, and the always amazing Netflix instant watch. But, it does have it's flaws, it breaks, online costs money, I've had problems with the controllers charging through wires, and it doesn't have a blu-ray player. But I still love it. The PS3 basically has none of the cons the X-Box does, and almost all the same pros. But I dislike it, why? Because I find the controllers hard to use, I never notice a difference with blu-ray, blu-ray makes things cost more, I don't like the dashboard interface as much, I think that that are better games for the 360, and PS3 isn't owned by Microsoft, so they don't have the amazing capability to do whatever they want with there system.
But overall I'd say they're about equal, and the debate should just be done with. No one is going to change their opinions, no one is going to win or lose, so shut up already and let the thread die.
