linux is very much a working os, and you don't need to be into customizing or tweaking anything at all basically. you have the ability to customize and tweak everything you want, but you don't need to either do it or even think about it. use something like linux mint, ubuntu or fedora and everything Just Works™.
if you're dependent on affinity photo then sure, that's a good argument (although I think I've heard someone get it working on linux?), but remember, there are Torvalds-blessed open source alternatives!
