Yeah of course, neither are perfect. But PES, compared to FIFA, has always offered a much more realistic overall experience. Look at PES 4 compared to FIFA 2005. Look at the old ISS Pro Evolution games compared to FIFA 2000/2001. Look at the past couple of years' comparisons. You'd have to be an imbecile to not see it.
lets talk about the recent games where this is reversed. I seem to be able to remember buying Arda Turan in 2008 and beating the entire team with him on the hardest difficulty in PES. This use to be true but FIFA certainly plays more realisticly now and if your still comparing it to the 1999 fifa when you was clearly not playing football how it is meant to be played (ie having 6-5 thrillers and finishing with 8 men) then maybe you hsould try FIFA 11 for an extended period.
I think alot of it is how people play, FIFA is a better representation with some major exploits that make people ruin it. I prefer to play football games like arsenal and try score that perfect goals, after all there only games, others seem to get more enjoyment out of running down the wing and cutting back for a tap in, ala FIFA
as for the above comment on fifas lack of individuality, this is true, they are way too gimmicky and i cant stand the guy (rutter?) whose too busy selling these gimmicks to fix up the game. they did seem to think that by giving C ronaldo and Robben and Messi their own running animation people would be fooled into thinking players were individually represnted, but PES is no better on this
