I was using Ubuntu in the past (Hardy Heron, Karmic Koala, and so on). I, for once, liked Unity. I liked, back in the days of Google+, how easy was to find fellow users and get help on any topic that arose (and boy, did I need support back then... rare was the week that I didn't get any error, specially after trying some new software and breaking some dependency). I remember how heated arguments were in the community when Canonical wanted to move to Wayland, and all the rage there was around it (and here we are a decade later, and most distros are moving to Wayland anyways). When they pushed Gnome as the main flavour, it felt like a downgrade to me.
About that time, I happened to buy a Surface Pro with Windows 10. I started using some software that had support only for Windows (or MacOS, but there's no way I'm getting a Mac after the lengths Apple went to break support for iPhones and iPads in Ubuntu). I also got Microsoft365 for the cloud storage, and Office was an added bonus. The interface was more similar to Unity and it worked way better than previous windows.
So I ended up uninstalling Ubuntu and going back to Windows. I know, I'm a lazy user, but I just want something that works and it's available. And no disrespect to the OS community, but some alternative software is not up to par with commercially available software that does not have a Linux version (not talking about games, Steam has done great advances in that regard, but rather illustration, design and publishing software).
If I had to go back to Linux, I may try Ubuntu, but I doubt I'd have the patience to stand all the problems with dependencies, unstable software, and so on.
That said, when I moved to live and worked abroad, I setup my father's computer with Linux Mint. He was already using Libreoffice in Windows anyway, so it wasn't hard to do the change. He uses his computer just for writing, browsing the internet and listening to music, so something stable and simple was a good fit for him. He just does software updates for the applications, and only updates the core system if my brother or me are around to help, so he hasn't had so much trouble.
