Man, my entire life I've been going back and forth between Gnome and KDE, I just settled (again) on stock Ubuntu (for some months now) but now that I see this video and the grass looks greener, again.
Guess I'm installing KDE Neon tonight...
Edit, I have to say that for the kids I'll stay on Gnome, it's very recognizable for them when compared to the iPads they use at school, much more so than KDE (and Win10 for that matter).
I recently decided to give stock Ubuntu with Gnome a try, coming from KDE. After about two weeks of missing some of the simple pleasures of KDE, like being able to right-click in the file browser to create a new file or resizing windows to the left/right side of the window with Meta-left/right (which is somehow buggy in Gnome), I landed back in KDE-land with Neon.
I briefly toyed with the idea of Manjaro, but am not sure I'll be able to install some software that is readily available as .deb.
I have been using KDE as my daily driver for both work and personal computing for five years now.

It's been possible to create files in the file browser (in Nautilus/Gnome) for as long as I can remember – you just have to have "templates" for the files you want to create in your Templates directory (e.g. "C file.c", "Text file.txt"). That being said, unfortunately this is one of those things where Ubuntu and Gnome are objectively worse than they were ten years ago – due to the changes related to renaming files in Nautilus, you can no longer give your new files a proper name as you create them, but have to manually rename them afterwards. Compared to all the clicks that takes (with typing in between), it's faster and more convenient to just click "Open Terminal here" and create any files you need with touch.
I don't know of any problems with Super-left/right, though.

Reminds me of another thing I love about Dolphin: hit f4 and a terminal pops up at the bottom of the window. That feature is addictive and I had withdrawal symptoms when I switched to Gnome (again) :)
Usually small things get to me like, Kmail won't keep my emails de-collapsed, or Kwin puts a border around Firefox so my tabs are not at the top and I have to aim (true for Gnome also btw), same goes for VScode. Or I want to use git over sshfs but KDE uses kioslaves and not gvfs so it's not a normal FS if you mount ssh in dolphin. Stuff like that.
Gnome usually make me miss some configuration options or they remove them. But as I grow older I get better at accepting defaults and I think Gnome will capture me once and for all soon. I do like how Ubuntu looks ootb (I only set dark theme, autohide the panel and keep 4 virtual desktop at all times (normally they are removed when empty)).
Sometimes I choose Mate (similar to XFCE I guess). I like it a lot but it just doesn't look that good (ark-darker makes it better).
For the record, I prefer SSH-via-kioslave over SSH-via-fuse. On my previous work Macbook, I'd bind it as "normal filesystem" and that worked great until I suspended my laptop or disconnected the VPN, at which point filesystem semantics are a giant drag on the experience. If implemented as badly as on macOS, it makes your file dialog and command line access hang.
At least kioslaves handle disconnects gracefully and are right back in service whenever your network is, without having to remount anything.
