FI wins it for me as best of the three, and I'm not that into Italy oddly enough. It is the maps, more rough, gritty and detailed. There are seemingly more terrain elements that further immerses me into the games. It is becoming harder to play a map with buildings and trees placed on top of what looks like grass carpet, with little to no other terrain details, as you will see with some Normandy maps. That is just my preference though. Normandy has some great, more detailed maps. And you get a wider range of tank variants that keeps me coming back to it as well.
