OpenSUSE Linux Tumbleweed with KDE Plasma desktop. Mainly because it has regularly updated software and it is very stable despite of this. And even if something would break I could just boot from a working snapshot automatically made just before the update. KDE Plasma desktop because I can customize it quite heavily to fit my workflow the best and no other desktop allows me this. And it also looks best to me. I also care about security and privacy quite a bit, and I trust GNU/Linux the most when it comes to this. It is also the most perfect OS when it comes to software development. Well Gentoo was even nice than OpenSUSE, but unfortunately I do not have the time anymore to compile everything and packages come in handy. Another thing I care a lot besides privacy is openness and user freedom so closed/totalitarian OSes like Windows and MacOS are out of the question for me.
