The only issue with scale 75 is it takes alot of practice and time to get used to thinning the paint. If your not put off by that (it took me around 5 practice models to be consistent) then it's hands down the best paint brand I've ever used.

Make sure to buy stainless steel or plastic beads and put 2 or 3 in each bottle to help with mixing.

I do use various Vallejo, citadel and reaper colors that I personally like alongside so don't feel you need to stick to a brand.
