I was distro hopping so hard I even ended up using FreeBSD for a while, but if I had to guess I would say Ubuntu accounts for most of my previous Linux usage.

It might be worth noting that I am/used to be a macfag at heart, ever since I started hackintoshing back in the glorious days of Snow Leopard. And even though the latest macOS releases have been really testing me, Apple still has me by the balls when it comes to the work machine.
Still, everything else, from the gaming desktop to servers has been converted to NixOS.
