Okay. Your Arch Linux review ends with naming your favorite options which include Proton, Microsoft and Adobe. As you don’t seem to mind using closed source software, did you have a look at WPS Office (Some Linux distributions include this), SoftMaker Office (Available for Linux and Android), Zoho Office ?
As for The GIMP (People have complained about its project name, but developers refused any changes) : From what I read Krita and Inkscape seem more promising. Krita has David Revoy as open source advocate, vocal on Mastodon : www.davidrevoy.com
