I'm in a similar situation.
I'm still using MacOS at the moment, but if I can get some decent image editing and vector application running natively on Linux, then my next computer will be a PC running some version of Linux (I haven't decided which one yet).
The only other "pro" software I use (Davinci Resolve) already has a linux version.
If not, then I'll have to buy an Apple computer again - but I don't really like many of their decisions made in the last few years, so I'd prefer to switch to a different OS... and Windows 10 is (for me) almost unusable due to my low frustration tolerance.
