The choice between a gravity and siphon airbrush is mainly dependent on the kind of output you're looking for. Gravity airbrushes will be the perfect option for you if you want to have outstanding lines with your work, or if you need an airbrush which can spray with low air pressure. Siphon brushes are known to be suitable for fine lines and detailing as well, but many artists prefer the gravity brush because it doesn't waste a lot of paint during the application process, unlike the siphon brush.\r
