Did a fresh install of Arch (after I nuked my Linux partition in favor of more Skyrim mods) on my notebook, and installed Deepin as the desktop environment on a whim. To an extent it's really nice-looking - smooth and modern-looking with everything being pretty well integrated; you can even have the dock/taskbar set up to emulate OSX or modern Windows with a couple of clicks. A lot of it is kind of like what I imagine Budgie or stock GNOME 3 could've been if they weren't terrible.
It's not perfect; theming support is hit or miss, and some of the stock Deepin programs seem to ignore themes entirely. Confusingly enough, this includes the file manager, despite it being the program of choice in Deepin's own theme previews. Additionally, while the built-in wireless network applet is much nicer-looking than nm-applet, it lacks support for WWAN connections; as my primary connection at home is LTE I'm stuck using nm-applet anyways, unless I want to set up a script to auto-connect in the background and hope I don't need to manually reconnect or disable/reenable the WWAN card.
Anyways, it's nice enough and fast enough for my needs, even if it's not as stylistically customizable as Cinnamon or any of my other go-to DEs. I'll probably puke up a fresh screenshot once I have the icons and Conky tweaked to something a bit more palatable.
