It’s definitely a preference thing. It’s funny though Dru Blair has CM-SB’s for his classes, but every technique used in the classes could easily be done with an Eclipse. If you know the proper technique, there is really no need for a super fine control airbrush. They definitely benefit the hardcore “freehand only” painters, depending on the size of the painting. I used to be one of them until I learned there were faster ways to paint and create more realism than freehand.
