My only issue with it is that it seems to try to do a little too much - but that is just a matter of taste.
Personally, KDE is the jack of all trades - it can do anything you ask it, Gnome goes a little too simple, I really like Cinnamon as a middle ground. But each to their own.
To me my favourite is xfce by far, it is so simple and fast without being too simple where it becomes an inconvenience. But, I need wayland so Gnome and KDE are the only really good alternatives for now. (Yes I know there are plenty of alternatives like sway, enlightenment, etc etc but no.)
Main complain is that it is noticeably slow and the GUI looks like an experiment to turn all pixels into clickable things. I think there is nice tech under the hood, but that's not what I'm looking for.
My main issue with Cinnamon is that fractional scaling doesn’t work well (to be fair, it only works in Gnome and KDE) but since Cinnamon handle bigger text very well, I have a nice experience just by checking « bigger text » in accessibility settings (while XFCE will scale text up but will keep the rest - mostly icons - really tiny).
Other than that, it’s a labor of love.
The Linux Mint Cinnamon version is actually pretty good: https://linuxmint.com/download.php
But also, XFCE has always worked well enough - it's lightweight, responsive and has most of the features you'd expect, albeit little to no eye candy.
