Personally I didn't like Deepin and I didn't really use it for long so I can't say much about it. Anyway, it is part of the the extra repositories of Arch, so you can expect a current and maintained version.

It should be the same for other Arch based distros. Just stay clear of Manjaro. It should not be used by anyone.

gentoo?

Try arcolinux. It's normal arch + packages you select + a pre-customized DE or WM

Solus does ship with deeping, if you are into are consider arch itself or endeavor or manjaro, manjaro does ship with deeping out of the box.

I remember using Manjaro Deepin when I was first getting my toes wet in Linux many years ago. It was smooth and the UI was better than Windows even. Can't remember why I stopped using it though maybe I got tired of it or the Manjaro/Deepin bugs.

If I'm being honest, if you can't use deepin distro I wouldnt bother. Remixes are nowhere near in terms of quality

I can't for the life of me setup DDE on fedora properly!!! I've tried numerous tutorials but it always ends up janky and not working!!!! I'm simply looking to explore other distros that the same old KDE, gnome, and xfce....
