Personally I’ve been on KDE for a few years, I love the way I can customize my workflow, from the default apps to the panels layout. The KDE team has made fantastic progress since I’ve started using it, and it’s now very stable and feature rich. I’m very excited for the upcoming Plasma 6
And as a reminder to everybody, please donate if you can, no matter what software you use. Especially if you’ve been using that DE for a while. Open source projects like these are always in need of funding!
