I've had Debian servers for years, but Linux Mint was my first DE and real substitute for Windows.
I like how it was easy to get started with, and provided a simple transition for everyday tasks.

Unfortunately I kept stumbling upon some things, which were just too big of an issue to deal with.
For example the file-picker in Firefox. It was this dumb feature-less substitute, which didn't show previews, didn't allow to navigate to a written path, and didn't show pinned shortcuts.

This, as well as some other things, made me switch to KDE, and I'm really happy I did, because KDE is much closer to the Windows experience, which I've become accustomed to for years.

But since my install was originally with Cinnamon, now I'm having both Cinnamon and KDE packages, and it's all becoming very cluttered.
For example I have 2 update managers in my taskbar. Both with seemingly different updates.

Furthermore, my OS has stalled COMPLETELY on several different occasions.
Like, complete freezes. No way to restart. Hard shutdown required.
I assume it has to do with my custom Firefox, which often has 300+ tabs open. But many are unloaded, so I don't see how it's a problem?

I'm thinking about switching to Fedora, or at least dual-booting for a while.
But I've always used Debian, so I'm hesitant on having to re-learn all terminal commands (or, you know, how things are done).
Kubuntu seems intriguing as well, but I want to have KDE 6.4, and maybe even Kubuntu isn't as stable as Fedora.
Arch also seems intriguing, but at the same time a bit frightening. I just want a stable desktop.
