Debian – I just wasn’t ready for it. Got told “oh you’re using Mint? That’s nice but you should try out Debian it’s the Real Deal™” but the reason I was using Mint back then in the first place was that it was my first step out of the Windows ecosystem, I was scared shitless and didn’t understand anything. What do you mean I don’t get a huge pretty start menu?! How am I supposed to find stuff then?!
Obviously, yes, but at that level of knowledge as a user, you either don’t know about that or don’t feel comfortable enough to deal with it.
