I have numerous machines and use several. On my main, KDE because of all the customization. Widgets, window styles, colors, themes etc. It's really like exactly how I want for maximum efficiency and productivity.
I've got gnome on my hybrid notebook and my transformer pad because gnome with Wayland is amazingly compatible with touchscreen.
I have one machine running Elementary which has the Pantheon DE it's kinda like Gnome with modifications.
And finally, I have an older system so just for efficiency, LXQt.
I do enjoy trying out different ones and especially more esoteric ones that I occasionally come across.
