I had a look at COSMIC on Fedora [1]. It is fast, stable and usable, but feels little unfinished (it is an early version after all). It is not my cup of tea (maybe I am too comfortable with KDE Plasma 6), but I am glad that there's a new solid option for a desktop environment. And unlike other with DEs, where interest and development quickly fizzles out, this will probably last as it has the System76 backing.
One issue that I had is fractional scaling for Electron (and older X11) apps on Wayland (same issue with Gnome and most DEs). Apps are blurry. It seems that only KDE Plasma figured it out. Plasma has an option "Apply scaling themselves", which just works.
