i certainly enjoy using .50 jt splatmaster paint out of my ego 08 with a conversion kit, quite fun and cheap, i was mowing people one day i used it in the woods shooting through stick bunkers and grass, they got very frustrated with me because they couldn't hide
if you can get a gun or a conversion kit for cheap and use it with an existing gun i definitely suggest trying it. if you play pump for one weekend and instead of buying $100 in paint you can get a conversion kit and a spyder rapid-E loader and a case of splatmaster paint and try it out, i certainly enjoy it but it is up to the individual, everyone who i let try it at my local field thought it was fantastic. i even played with some little kids and showed them that it didn't hurt in front of their dad, i've shot myself point blank in the hand with it to prove it.
everyone has their opinions, for me i like both forms, all paintball is enjoyable to me.
