KDE is my favorite DE by far and it is very much the most advanced environment I know. The integration is the best and the ability to tweak everything is great.

Personally I use i3 90% of the time and use many KDE applications. KDiff, Dolphin and Gwenview are my go to for me, well that and ranger the console file manager.
