At this moment, I've already tried almost every DE excluding some tiling wms or things like LabWM/Openbox/IceWM. I've spent most time tryings these DEs on Fedora, and for me these years with Fedora were the most frustrating ones in my whole Linux experience. I really loved Gnome, but Gnome 44 felt so unstable for me (Nautilus freezing when context menu opened and both mouse buttons pressed, constant crashes of some internal components like tracker-miners, memory leaks in Gnome software and so on). Mate and Cinnamon both were great, but on my current rig Xorg just doesn't work for me, especially in some games utilizing DXVK when FPS exceeds my 144hz refresh rate and everything becomes too choppy. Budgie looks great too, but last time I tried it it was impossible to switch to a different keyboard layout on a lock screen, and the whole DE just was constantly crashing. And most of my time I spent on KDE starting from 5.14. From version 5.22 I fully switched to Wayland session, and while it was a mess until 5.27 released, which fixed constant freezes when your clipboard had too many things inside, but with latest Fedora release the whole experience became a nightmare for me - KDE applications were crashing, default power profiles made my laptop instantly shutting down when something power intense was started on a discrete card (AMD RX 6600M), and then I just decided to try a new Debian release in a total despair from my whole experience. So I installed Debian with KDE, set everything I need, and.. oh my god, I think I finally found my zen. KDE 5.27 with Wayland works SOOOO stable I just couldn't believe I wasn't running it on Xorg. Laptop stopped shutting down when discrete GPU was utilised on battery, it always wakes up from sleep, it just works flawlessly. I even guess I never was more happy in my whole life xD
So looks like Fedora was my main problem for the whole time, and maybe I should try Gnome on Debian someday, but as for now I'm just so tired, and I just want my computer to work without trying to surprise me with sudden instability when I really need to work. And sorry for my long boring story not even really related to DEs, but while I was writing this comment for some reason I thought I should say about all these things, heh
Sounds like a great idea, I'll definetely leave one :з
