A lot of people like the Ubuntu/Debian variations. I just don’t. Probably due to history and comfort. I started out on the Red Hat side and I’ve just stayed there.
The worst part of changing over is the package management system change. I'm using Mint these days and have for a few years now, but I still miss the RPM command that would show me the packages in order of when they were last installed/updated. That was really useful when building documentation. Haven't figured out how to get the same info with apt.
I’ve thought about trying the others and I don’t use the terminal all that often but I know I’d be typing everything in wrong for a while, having to learn new settings, names etc. Like you say, history and comfort.
I tried Neon from KDE a while back, still ubuntu, but it was like windows. Lots of huge updates and any given one might break something and then it takes a few days for an update that fixes it. That is, Assuming the internet isn’t what broke. That’s what happened to me, couldn’t connect to the software repositories so I went back to Kubuntu. Neon is basically cutting edge Kubuntu. Could almost call it beta Kubuntu.
But there’s just so many things that Linux does better than windows.
Software to do almost anything you can think of and it’s for free. All in official software repositories with the code open for all to see so it’s safe from having malware, viruses, adware etc.
That and having a Home folder where all your files and settings go, makes backup and restore a cinch as well as migrating to a new machine or slightly different OS version.
No 30 minute shut downs - restarts for every third update. No upgrades or software being pushed at you.
None of your personal data is being mined by the developers of the OS so they can market to you or share it with “partners” so that they can market to you. That’s a huge one right there.
Linux is falling behind though with all the new touch devices. Not talking phones but tablets and laptop/tablet hybrids aka 2-in-1s. Gnome is about the best on the Ubuntu side but it’s a very limited OS in that you can’t change many settings because there aren’t many. Ubuntu itself is making the swap to the gnome desktop so that may change. Then again maybe Ubuntu is headed for simplicity to attract a broader base of users and devices. The touch functions on gnome work fine. Only thing it doesn’t have for most devices is screen(display and touch) auto-rotate. There’s other distros that work with touch but even when you rotate the display manually, the touch doesn’t rotate with it which makes it kind of useless.
