You don’t need to change distro in order to change desktop environment: just install gnome/kde/whatever if you want to give different ones a spin (you don’t need to uninstall your current desktop environment either - you can have multiple ones and choose which one to use when you login)

You can try Niri - it is a tiling, scrollable wm, a lot easier to use than i3, I’d say half way between i3 and a full de.

terminal only

If you want something that looks different you wanna find a different desktop environment(DE), most of them are avalible on most distros. I’d pick a distro then a DE that they offer. You could try these DEs you haven’t already tested:

• Cosmic, think tilling + gnome-like interface. It softens the learning curve for a tilling WM a lot if you’ve got other options. Fedora has a spin with this in if you liked fedora.
• Budgie but can be quite similar to others
• MXLinux with Fluxbox could be an interesting choice, its usually used on low end devices but its pretty snappy on anything else. Or Fluxbox on any other distro but MX is the only thing I can think of with it as an install option.
• If you don’t mind something older, you could look at CDE or NsCDE, although I can’t remember how involved the install process is.

Other than that, your options for non-tranditional desktop environments are probably just other tilling ones(i3, hyprland, ect) or scrolling(like niri). Or customising one of the others, KDE can be very flexible for that. You’ve gone through a lot of the main ones.

As for distros, there’s a lot, most will have the same set of desktop environments though. So, the same look and feel one you get past the install and package management etc…

If you don’t mind going outside linux land, haiku can be fun. Completely different OS though…

If you want to break out of the windows mold, tiling windows managers are where its at. You’ve already explored that route with i3, and there are other alternatives, but they all have a bit of a learning curve unfortunately. hyprland might be worth a try. I’ve only dabbled but I did remember it being a bit more beginner friendly than i3. But be prepared to be confused, read a bunch of forum posts and edit config files for a bit.

I’d say PopOS with the relatively new Cosmic Desktop could be something interesting for you to try of you don’t really want to go into configurations that much. It has floating and tiling windows that you can switch easily.

Carchyos or Endeavour with kde maybe.

If you want to go out there, tiling window managers are neat. I want to try hyprland at some point as well.

try nixos / guix

GNOME and vanilla Xfce are fine, but you can also try ElementaryOS as a distro.

I’m currently running CachyOS, where I installed Hyprland and ML4W dot files (basically a well refined set of config files for Hyprland) alongside KDE Plasma. ML4W (MyLinux4Work) has great YouTube videos detailing their installation process.

Hyprland, like i3, is pretty amazing to use once you get used to it, but sometimes it can break, so having the option of rock solid KDE right at the login screen is a nice bit of insurance.

CachyOS is based on Arch, so you’ll need to get cozy with updating and installing software, both from the repository and flatpak, via the terminal. If you’re not already comfortable with that, it’s a great opportunity to learn.

If you want to break out of this and find something new without too much of a learning curve you could try Illogical Impulse

It’s hyprland, modded and more avvessible.
