i vote airsoft ten fold, i have a tokyo mauri VSR gspec that shoots over 500fps and i can hit a target accurately from around 100yrds...i would go gun to gun with any paint ball gun, i have and i had them out before they were able to see me. airsoft rounds are cheaper but i have seen guns anywhere from 20$ at wal mart up to 3000$ for machine type guns with 5000rd elec mags, so the guns are priced about the same but 4000rds of really good bb's were 26$ and some change...try buying paint balls for that, i just think airsoft is way more accurate, hurts just as bad, and does end up being cheaper.
