Hello, i'm planning to buy an airbrush very soon (mostly for the 7 GW vehicles i've got to paint, the one i'm going to buy this year and my urban town project).
I've already practiced when i was a kid with simple action plastic ones (the same stuff that GW is selling now in a funny design) and now i'm going to buy a real 2 action one with a compressor.
My question is:
what's the differences between gravity feed and bottom feed, what's your preferences, what's the best for hobby painting?
I was aiming at first bottom feed, because that way you can put it somewhere if you have to turn your tank or do something else for a few seconds, but now i've got some doubts as most of the video i've seen are using gravity feeds

Thanks in advance.
