Fractional scaling on KDE + Wayland is working pretty well for me. I came from Windows, then macOS, I have been very happy with KDE.

Adobe is an issue, there are many analogs though. In place of Photoshop you could use Photopea, Krita, GIMP. That said I understand that people generally love their Adobe apps.

KDE is reasonable but the problem is that not all toolkits are made equal. If you have to fire up something that uses Gtk, which is somewhat inevitable, it really pokes you in the eyes.

I tend to use Adobe stuff because it is literally a decade ahead of the closest open source software and is not expensive on a monthly basis for what you get. I could not get close to what I do with open source software. I have tried. I mean just the AI denoise in Adobe Lightroom can't be touched by anything. I wish it could. And I wish I could contribute to something open source to do that but I'm not good enough at it :)

Both GTK and QT have modules to integrate the opposite toolkit themes seamlessly.

For QT5/6 software into GTK desktops, there's QT5CT.

My XFCE4 desktop running QComicbook (QT5 comic viewer) both have the exact same theme, Zukitre. Ditto with the icons.
