The thing I will say about H&S brushes, they are the most innovative and versatile airbrushes on the market.
- Nozzles range from .15-.6mm, and are the easiest to change.
- Nozzles are large so they are easy to handle and see(the "Soft Brass" thing doesn't really matter, the needles/nozzles have the same taper, you couldn't damage the nozzle by trying to push the needle through the front if you tried)
- Paint cups are removable and they have "Micro Cup", .2ml to .5ml
- Trigger tension is adjustable without removing the handle(Infinity only)
- Best Quick Set handle(though I never use it, so its null and void to me)
- H&S is the only airbrushes I know of that have an adjustment for the air valve tension.
Basically what it comes down to, if I had to own just one airbrush, it would be the Infinity, because the accessories and options available make it the most versatile one on the market. Just my opinion.
I do love my Micron. I would say it is the best detail gun on the planet, but it I can't use it for everything.
