This is something you're just going to have to feel for yourself. I ended up with the handle grip after about 1/2 hour in the store holding both types. I've got large hands but the barrel grip just seemed to point towards more hand fatigue for me. I also preferred the trigger switch, but it was primarily hand comfort that made my decision. This is like the paper/plastic or boxer/briefs decision - which one makes more sense or feels better for you?.
