Definitely for sure! The only thing I wish they would add is the ability to have icon zoom for the task-bar and intellihide to be able to mimic a dock and not use something buggy such as Latte Dock 😵💫 and sadly Plank doesn’t play too well with KDE since the desktop widget gets stuck there, at least on my install.
The one thing I don’t like about Cinnamon is that it doesn’t play nicely with flatpak theming at all. KDE seems to apply themes over flatpaks with no problem no matter the distribution. If the Mint team built into Cinnamon desktop these theming capabilities, I’d use it over KDE all the time happily.
