You can try Leonardo for your tablet. It's a really nice one but with certain limits, however in my case they're not critical. There are amazing touch controls in it and the quality of my works with it are very high. I adore to use it for random drawings and sketching.
Sketchbook Pro is a good one too. It has tow versions, for desktop and one in the MS Store. I prefer the desktop version. I recommend you Sketchable too, it's one of the best professional drawing apps.
I like Concepts very much too, it's one of the most innovative in case of its tech stack
and functions too, it's based on infinite canvas vector. I saw also many nice reviews about Clip Studio Paint.
