Alot of full time teachers might have the facilities, space and equipment that is closer to ideal.
Part time teachers might have smaller classes, more individual attention, and only keep people around they like and work well with.
Full time teachers usually have to teach "less than ideal" students such as children (personal bias of mine!) and people who just want to pay and hang out twice a month.
Part timer teachers are making their living some other way, so they may not be practicing as hard as the full timers in terms of competition training or their personal practice.
I've managed to figure out a way to have a nice school (in terms of the physical space and equipment) while still teaching part time. The only down side is I don't make much off it financially. But it's tons of fun!
