I would recommend '12 or '13, as they're basically the same. '11 is great on the field and I would recommend it, but it has way too many glitches and bugs, particularly concerning player progression. I believe there is a workaround, but it seemed pretty convoluted, involving the adding and subtracting of patches and/or tuners. I honestly don't remember, but it seemed like a lot.
I'd go '12. It's one of my favorites of the series, overall.
