ive played over 400 games on the 360 version and moved to the pc version when my console died of the 3 rings of death
the pc version if u have a fat pc looks the best with all detail on max but the online play totally sucks!! almost every game i play i end up pairing with some italian spanish or german with a totally crap connection that makes the game almost unplayable...
the connection looks good when u search for rooms with 3 green bars but when the game starts its a joke! and most people select english even when there from another country far away
the xbox live version on the other hand must have some kind of connection limit that kicks laggy players and pairs u with people on the same ping in same location that makes most games very playable.
and dont forget the pc version is easy to write cheats for! sometimes i find when beating players on the pc version and very often italian cheating scum bags that some how they manage to lag the game and get a default win or the games turns so laggy that its unplayable for me but they seem to score lots of goals! they cheat in real football and they cheat in online football....
ok i take that last comment back only joking

but it does seem to happen often from players of that part of the world.
