Have you tried Open Tablet Driver (if your tablet is supported)? I use it on Wayland and it works perfectly for me, but I’m not an artist and I only use it to play osu!.

By highly configurable, I meant that you can configure it exactly to your needs, in the same way that you can with Arch.

I use NixOS for University and would highly recommend it if you want a highly configurable system that’s declarative, however, NixOS doesn’t have great documentation for certain features and usually does things differently, so you’ll have to learn the Nix way of doing things. On the plus side, I’ve never been unable to fix my OS when it broke, you simply rollback, or if there isn’t a suitable rollback, you can plug in a live usb and set the system to use a specific commit (can’t remember the exact command for this and that’s presuming you store your config with git). Also according to these statistics nixpkgs has more packages than the AUR.
