Both Vallejo and Citadel paints are highest quality paints for miniature and wargaming painting. Citadel is the best choice for painting Warhammer minis and it is one of the bestselling products from Games Workshop. Citadel is a trusted choice for base coats, adding shades and technical details for Warhammer. On the other hand, Vallejo has just an overwhelming choice of sets, stains, effect and paints for any kind of model and miniatures, and situations you may think of. Hands down they are the most versatile brand. Yet, one of the most expensive as well.
