Better than paintball by far; more realistic.
The site me and my Dad's team use is also host to Painball games. They always look ashamed at their tube-with-a-ballon-ontop as we walk past with our replica weaponry and proper gear.
I admit airsoft requires honesty in comparison to the obvious 'being hit' status that comes from paintball, but that's what makes it somewhat more fun as it has a social wuality to it, plus the marshalls are amazing at their jobs and certainly deserve to were the illuminous jackets.
End of the day it's personal opinion I believe.
Although in my heart of hearts I'd say Airsoft's more realistic and fun; If you're going to enjoy a day out pretending to be a soldier and have a laugh, do it as real to the experience as possible and have a blast as you make giant, stocky guys yelp as you bury their left buttock with flying plastic, in my opinion.
that is some fun stuff =D
the guns being more realistic is better by far than a giant balloon on top, plus it does hurt a bit
