I used to do it all the time when I first got airsoft. We played milsim paintball so it was pretty similar. After a while we switched over to all airsoft because it's just simply a better game. I couldn't wear all my gear because of the paint, and the gun had to be cleaned every time. (I only used semi-auto for fairness too)
The other players were good, called their hits, and things were pretty fair. Airsoft in general had the advantage, because it could shoot through smaller openings, and is a lot more accurate. Airsoft also fires forever, whereas people are always breaking balls and running out of gas with paintball guns. Airsoft was quiet and stealthy, and paintball is loud and gives away your position.
I loved spending a lot less money using airsoft than paintball....gives me more money for guns.
