well i downloaded both demo's and gave them both 3-4 games each and i can honestly say that there is a massive jump in quality with PES this year,the passing has been refined,no more players aimlessly passing the ball nowhere near where you want,now,if it goes astray it is because YOU put it there
graphically it looks stunning compared to last year and the only complaint i have is that there has been 3 occasions where it "froze"b for a split second but their is not an issue i expect to see in the completed game.
as for Fifa,i felt like the ball was attatched to my laces witha rubber band and the feel was just all wrong
