IMHO.
I always tell newbies to start limited, open, CO or PCC.
Minimal reloads for them.
The more manipulation, movement, stage breakdown, etc. etc. - it gets too much in their head and that's when i commonly see them get confuse.
Along with directions from all shooters willing to help newbies...
Now typical average competitor, assuming the shooter has a top quality pistol and accessories for either division.. i would say whatever fuels your passion. LOL
