On the other hand, I find the gravity feed easier to clean when I am doing several colors in a session.
With a gravity feed, your color cup won't fall out of the airbrush while you are using it. Of course, if your gravity feed doesn't have a lid/cover, you'll dump the paint in a bit of inattention.
My now current "do all" airbrush is a Harder & Steenbeck Evolution Silverline M. It is a side sucker, meaning I can switch from a color cup (gravity feed) to a color jar (syphon). The find pressure control (optional) is what sold me on the brush, as well as the paint control which is part of the Silver- line M.
The color cup and jar screw into the right side of the brush, so there is no damn way the color cup will fall out of the bottom of the brush, I can also rotate the cup/jar so they are level, despite what angle I hold the brush at, and the cup has a lid, so it minimizes a spill if I don't pay attention and set the brush back in the holder (or, thought I did, at any rate).
