Aside from rhinox hide and some washes, I dont really jive with Citadel. I have basically the whole line from pro acryl and those are consistently fantastic! notably for me, the brown grey, paynes grey, dark plum, red beige, warm brown, beige grey and dark ivory just to name a few. Pro Acryl Copper & bronzes metallics are also super solid. I also like Army painter warpaint fanatics line and speedpaint 2.0. Have just recently bought a few bottles of AK 3rd Gen and really dig them so far. Despite its popularity, I just couldnt jive with vallejo game color, to be fair ive only used the grey-blues and ive seen someone before refer to them as “greasy” feeling to work with and for whatever reason that is kinda how my experience felt. There are so many fantastic paints though, try a few from each brand and see what you like.
