Come to think of it since my last post #6, apart from switching sides quite often in both fixed wing and helicopters, I have flown choppers for sling work where it's much easier to lean out left side with the collective on my left (eg Bell 47, Hughes 269). I have also flown aerobatic fixed wing aircraft where seating is fore/aft (eg Pitts Special) where the left/right seat issue is irrelevant anyway.
