PS3 vs Xbox360

Ok, lets face it. If you are a video gamer you know its all about PS3 or xBox360. People who have the PS3 claim PS3 is better then the xbox360, and people who have the xbox360 claim the xbox360 is better then the PS3. All i know is i have a PS3, simply because my boyfriend claims it is better. But here is the real question, which one is better? Tell me your opinions and WHY you believe that. I mean according from what i know the PS3 gives you the availability to watch Blue-Ray DVD compatibility, if you love watching movies and playing video games obviously this may be a reason why you chose PS3. But i guess it depends on the kind of games you like playing right? So this is clash of the titans: PS3 vs Xbox360... what do you chose and why?
