I'd tried the wii PES 2008 or 09 once before and hated it. Got 2011 a few months back for cheap and gave it a proper go last night (Tyne-Wear derby) for the first time.
Takes a while to get used to, but pointer controls for passing, dragging defenders, and - oh my - crosses into the box - are amazing. Oh, and penalty shootouts rock, since you can gamble on top corner shots and run the risk of glory vs woodwork.
This week Ive played the PES 2012 demo, Fifa 12 demo, PES 360 and PES Wii and the latter is the best of the bunch. Probably up there with PES3 and ISS Pro 98 for playability.
