That is a matter of preference slava, since they are kinda different airbrushes in the function. The Hansa 381 is a gun with a combined
double action. Means you dont have to press for air. Instead you move the trigger back and air starts, then a few more and the paint also
begins to spray out. I have a H&S Grafo with the same system and it is cool, but you also have to get used to. One thing that is a advantage
of this system, you can not forget to shut the paint off before the air, even if you just let go it will do shut paint off and then the air after.
I guess the quality of the spray pattern will be very good with both of the guns and also the prices for spare parts are similar. If you want a
classic double action gun then go for the Velocity.
