I use mostly Tamiya acrylic paints, mostly on aircraft models (armor occasionally). They are practically odor-free, and work well via brush or airbrush (may require some thinning for airbrush use). Color selection is generally good (there's a few more colors I wish they had), clean-up is easy (with Windex), and they adhere well (though I always seal with Future (before & after decals), & Dullcote when a flatter finish is needed.
