I recently decided to, for the first time, own an entire paint range and got the war paints mega paint set. I am super happy with my choice. The paints for me fall between gw foundations (old) & their old basic paints. Color range is good price was great also came with a selection of their brushes handy little bit.
The warpaint Metallics are wonderful, I used to feel spoiled on the gws like I wouldn't find any better, but I am surprised at how solid and good they are.
While I like the army painter brushes for me nothing beats the p3 studio work brush. Local shop owner swears by them and one he finally had stock I got one, best purchase of a brush I've personally ever made.
