. Not very realistic guns
. very painful
I prefer airsoft
I would recommend airsoft for someone that is more into realism. Not just the guns are realistic but so are the vests and clothing. Airsoft being less painful is not a good thing because people can cheat. One of the biggest reasons I like airsoft more is because there is no paint to clean because the smell is just horrible and stains.
Airsoft is just slightly cheaper then paintedball but not by that much.
I would recommend paintball for someone that wouldn't mind spending some more money and doesn't care to much about realism. Paintball is better the airsoft because when you hit someone they will get out from the pain of getting hit. Paintballs down sides are the paint staining and the smell so I would recommend using clothing you don't need.
Over all they are both good sports but it just depends on what interests u have.
