Sony: 8.1/10
I'll just copy paste the relevant parts from this post.
Sony: Mag is totally amazing, will have to see if they can make it accessible but yeah its a definative moment for FPS online on consoles. Uncharted 2 was also fantastic. I was ready to give it to them right there. Final Fantasy XIV, hmm will have to wait n see im not too impressed because MMO = PC for me until proved otherwise. ICO game was pretty arty, not my scene but its an amazing thing anyway and have to give it respect. I liked their Wiitoo type device, but the demonstration felt really hashed together at the last minute. It makes me think that the 2010 release date for spring would be a soft launch if at all. Gran Turismo truely is a mega hit, its pretty big but seeing it likely slip from 2009 is as much a disapointment for me as it is an awesome experience seeing the WRC and Nascar type gameplay modes. Lastly that car racing game was pretty off the hook too. God of War was really cool too, but the unexpected hit for me was that car game! Man... Awesome stuff.
On the face of it I will probably give it to Sony marginally. Many of the 360 games aren't different enough, better enough from an equivelent multi-plat. MAG is something im wary of but the concept is totally fantastic and its definately one of the show winners for me and the Kart racing game was so slick and came out of nowhere. Joyride has nothing on it. Microsoft has more great titles but Sony has more special titles. For example Forza 3 is matched by not GT5 but NFS: Shift. In all I would give Sony about an 8.1/10 and Microsoft a 7.4/10.
