The latest acrylic paints are Polly-S , Model Master, and Aeromaster ( if you can still find them). There are others like Tamiya, Badger, Gunze-Sanyo and Pactra.
Testors does both acrylic and enamels...Basically, you have a lot of choices nowadays, it's up to your individual taste. I personally use the first three mentioned above. Some of the others are good for things like making colored lights, etc...
