Take it from a guy in your exact situation a few days ago,
I bought PES 2011 from Zavvi.com for £17.99 (now £29.99) and havn't touched FIFA 11 since. The gameplay is just so much better and more varied.
To sum up FIFA 11:
Pressure, pressure, pressure, pass, pass, lost possesion, gained possesion, pressure pressure pressure, 1-2 lobbed through ball, goal.
Repeat.
As the guy above mentioned, EVERY game is the same, wether it's Chelsea vs Barcelona, or Arsenal v Rochdale.
PES 2011 (my first ever PES since PES 5), is different every match, which is why I am having so much fun in Master League. You feel like you've earned a goal, because every goal is different and unique. It also has that unpredictability of how the match will turn out.
Get it, play it for a couple of days to get the bad animations syndrome out of your system and the game will open up and feel great.
Go download yourself the option file for correct names/kits and you will love it.
Hope this helps.
