I made the switch this year, having not played PES for probably a good 15 years. I second the PES Universe recommendation, their option file is great and they've also just released a classic file that has 20 teams that's really brilliant too (basically all-star teams of Man Utd, Arsenal, Liverpool, Real Madrid, Barca etc). The in-game menus aren't anywhere near as good at FIFA but I do feel like the gameplay really is much better. It's a lot less arcadey than FIFA, and more slow build, but I like that. It's more of a challenge than FIFA as well definitely.
