Running Plasma instead of Gnome for the first time in years
Trying Plasma for a bit to see how green the grass is as a longtime Gnome user. The last time I ran Plasma on my main desktop was version 5.11, I think? It's been a while...
By default, both Plasma and Cinnamon have a very similar set up to Windows.
However, Plasma is insanely modular and customizable, so if you're willing to take the time to, you can make it look as much like Cinnamon as you please. Given how simple Cinnamon's design is, I don't think it would be hard at all.
Plasma isn't as visually polished as Cinnamon. Go ahead and get your clock and CPU temp widgets in the system tray the same font size and positioning.
KDE feels a bit more cluttered because...I've said this before, KDE gives you every option under the sun, GNOME software isn't designed to do anything unless you add extensions to enable features, and Cinnamon is somewhere in the happy middle.
