I spent a few minutes setting up a Plasma desktop to resemble what I like about GNOME Shell. A screenshot doesn't do it justice imho. Application Dashboard on Meta, Overview on Meta-W, a Panel and Icons-Only Task Manager set to Autohide at the bottom of each screen, and the Tiling Manager.
As much as I love a good light weight DE like XFCE, KDE plasma has been the best experience on multiple distros including Debian and Arch. It's the closest thing to an accessible windows-like experience with all the customization you wish you had in windows with so many applets and widgets that fill in so many gaps in other DEs.
No need for anything particularly modern. Even on a ten year old laptop I've not noticed a difference (Windows, on the other hand, barely runs at all on that machine).
I've used KDE for more than a decade
Not just the desktop but the Ksuite of programs
Being able to setup a nice custom tool bar
Auto hide panels of a size that my decaying eyes can read
Doing update without having to troubleshoot afterwards :D
