PopOS! and base Debian , I used to have an old buddy (RIP Edge-0p) who was a die hard Debian fanatic and kept trying to usher me to get on the wagon but even from the beginning I had liked Slackware more. Now am on arch and my other older laptop runs void, and have a very old laptop that just holds some precious data for me from back in the days using FreeBSD , and I still have the original laptop I put linux on in late 93 at college , a 486sx lol. Imagine the crazy shift in computin and engineering to create what we have now. Cheers!
