What's your current setup? (Computer, OS?)
Short answer: A fairly recent Thinkpad running Arch Linux. The details: I use Zsh as my shell with no login manager. I recently started using KDE/Plasma after years of using XFCE as my goto DE. Why? To give it a go, mainly. I'm pretty happy with it for now, mainly for its WM, kwin, which is very versatile and customizable.
I discovered zsh with oh-my-zsh and I must say, it is way more productive than bash !
