I totally agree with everything you said Whiterook, but when airbrushing, Tamiya acrylics have quite a grainy surface and I've experimented with thinning and pressure. It's also much harder on my airbrush. I've burnt through two nozzles using Tamiya after nearly 12 years of exclusive Humbrol enamel use.
I used to be a Humbrol man until I read a few books about modelling. Now I use acrylics, enamels and artist oils...all for different reasons and for different purposes. The way I weather dictates what paint I use. Usually I paint the base colour with enamel. Clear gloss acrylic over that. Decals. Clear gloss again, then filters. Filters are very diluted enamel paint...usually with turpentine. This also helps dull down the gloss. Oil paint pin washes and panel fading...again with turpentine. Dries nice and flat. Then depending on what I'm building. An aircraft gets a matt clear coat then I airbrush smoke stains and add pastels here and there. For a vehicle I don't know yet...
So as you can see, all three paint types get a run with me.
