Same. I started with Ubuntu like a decade ago. I hated it and didn't really see the fuss, kind of gave up.

But then I started putting in tons of time in rasbian, and windows kept getting more and more.. Well, windows. I eventually realized how much more I liked working on stuff on the pi, and just needed proper hardware. That's also when I started to understand the differences between distros. I'm not flaming Ubuntu (I'm not really smart enough to have an opinion), it was just a lot of hastle for something I didn't understand the upside of yet.

Been wrestling with my first all Linux (Debian) box. It's a bit of a learning curve but there's this weird headspace it frees up. It does what I tell it. There's no random software that shows up. There's nothing I can't nuke. No surveys on my favorite BBQ dish in my Taskbar (true story). It's so godamn nice. It's the opposite of a black box.

Im getting another (3rd) box specifically to slowly replace my current desktop. Ill be fooling around with WINE and whatnot for the software I need for work, probably setting up a small windows partition for when I absolutely need it. But all in all I'll be 90% penguin by years end.
