Oh, it's been a long time. IIRC, I got good results using Tamiya paints. Then again, I was using an airbrush. Their acrylic enamels were easy to dilute with water than the oil-based paints with thinner. I do believe, however, that Tamiya has a line of small spray cans that may work better than Testors, although I've never used them myself. Simply judging based on my experience with the brand in other mediums. I believe Testors also has acrylic enamels and, arguably, a more diverse selection of colors than Tamiya, but that could be left to debate.
Again, my knowledge is a bit dated, and there may have been improvements in paint quality over the years. I would almost recommend trying different types of spray paint on scraps of plastic or cheap throw-away snap-tite models to see what gives you the most closely desired result.
