Well lets see here, I started playing paintball in the early days early 80s. It was the only game, airsoft wasnt around. Paintball changed over the years and moved into milsim type games or speedball arena bs. It wasnt until I found a copy of Airsoft international a few years back that airsoft caught my eye.
So there is by far more cheating in airsoft, just my experience, then painball. dont get me wrong there is still cheating in painball. But some times you just cant wipe all the paint off! So I play as close to real as possible with buddy I trust which lessons the cheating a lot.
Airsoft by far, to me, is the better game. Guns are more realistic and nos paint mess to clean and I dont have to worry about kids!
