I used Ubuntu once a few years ago but had compatability issues so I went back to windows. Not a great programmer but I'd like to learn. I'm not looking to do much gaming beyond DOOM2 and factorio. Mostly looking for privacy and a way to get back into programming (I have this pipe dream of learning Assembly). I'm not to particular on UI, I can use whatever.
Edit: https://distrochooser.de for anyone who stumbles upon this post with the same question
Many people have asked me this (I'm the certified neighborhood tech guy :P), I always recommend Linux Mint, with the Cinnamon desktop environment, or KDE. Ubuntu used to be the best one and it's still very good, but pretty heavy on hardware and they keep adding frustrating features nobody asked for.
Please please please, at the start, stay away from Arch and it's derivatives. I daily Gentoo, but you need a decent knowledge of Linux to use both. If you need help, post to the Linux community or DM me :)
