1.Personal choice
2.on playing online they are the same,,,some times PSN is better for mulltiplayer as each game has a dedicated server unlike Xbox live ,,,plus PSN is %100 free.(50$ for x live/year)
3.the only example of top of my ehad is unreal tournament III where PSN has mod support but x box live does not offer mod support feature
4.some parts of (some) games are installed (not the whole game)to improve the performance on PS3,,,,,xbox will get a feature later to install the whole game on the hard drive .
5.ps3 has been outselling 360 for the past 7 months or so on weekly basis.(360 has a lead since it launched one year earlier than PS3)
6.with the firmware updates every month on PS3 and bluray tech It's safe to assume that PS3 is moer future proof since developer will learn how to optimize the bluray and put big games on it.
7.I bough a PS3 7 months ago and I love it(I also own a PS1 and Xbox)
