Similar helicopter flight mechanics

I've always wanted to spend a bit more time on piloting in that type of games. I really enjoyed doing it in ARMA 2 and 3, but since then I haven't had many opportunities to play that way.

I've tried flying helicopters a few times in Battlefield, but the game is so chaotic that I never really felt like there was much point in trying to properly learn or practice it.

I see a lot of potential in WARDOGS, though, and with the upcoming beta I'd like to "refresh my memory" and get some practice beforehand. Unfortunately, I haven't had the chance to play WARDOGS yet, so my question is mainly for people who have already played it—especially those who have spent some time flying helicopters:

Which game has the most similar helicopter flight mechanics?

I currently have ARMA 2, ARMA 3, Arma Reforger, Squad, and several Battlefield games.
