Favourite Air RB Belt?

Since the introduction of Realshatter to the majority of the game what belts do you find best to run with?
Getting advised to run with the least amount of HEF rounds which usually knocks air belts out of the
choice except Germany.
Just wondered if everyone was having the same experience or is it a bias against this mechanism?
Full transparency, I play upto WW2 only.This is across allot of Countrys Allied and Axis for that meta
Also did a search but didn’t find much
