Whats better Call of duty 5 or Resistance 2?

I got Pes 2008 in october last year and thought it was brilliant. Recently i got Euro 08 and its a much better game. But then FIFA 08 is a great game too. So..... which game do u think is top at the leauge?

ive bought quite alot of movie tie ins so i thought "What games are the best selling crap?"
