For finicky GPUs especially, Pop OS is a good option. Also Manjaro's MHWD thing works great.
Before abandoning ubuntu altogether, you might want to try 20.04. For me it seems to be the goldilocks of linux for my MSI laptop. The kernel 5.15 also pretty damn reliable.
Kernels, tracker search engine, and a couple other things... problems that ubuntu has had forever and somehow never fixed.
Tracker, in particular, is a real pain in the ass if you have source code in your home folder. If you don't tell tracker to not touch those areas, it will bog down memory and processing to index it, every day, especially when you are playing games.
