- I had used it until 7.0 in the past and missed the simplicity of having one single platform (rather than Linux with its kernel and the many distributions all doing things differently).
- The excellent handbook
- Almost devoid of corporate influence. Linux is being steered into the warm and fuzzy corporate domain. Many big players try to get their IP adopted by the Linux mainstream. Canonical with Snaps for example, Redhat with Gnome, etc. The big tech players are the biggest kernel contributors now. It moves from choices good for customers to the ones that are good for big tech.
- Non-opinionated platform. Some distros are also becoming quite opinionated like Mac. I did try to play the Apple game for a while (like I said it was my daily driver since 10.2) but they kept annoying me more and more by deprecating things I used. I want choices again.
- Stable platform but with rolling app packages. For example if KDE comes out with a new version I will see it usually a day or 2 later.
- Couldn't find a Linux distro I really liked. I like minimalism but without Arch's elitism. Debian would have been the closest but I have bad experiences with major upgrades. What I would have preferred would be something like Alpine for the desktop. I looked at Adelie Linux which is exactly that but it was too premature.
- The ports tree is really amazing. You're always able to change default package settings and recompile them
- Jails are more powerful than linux containers, though they lack a framework a la docker. This is why I still use Linux on servers.
So this was mainly it :) Unfortuantely running KDE did require installing some linuxisms like Dbus but overall it's not too bad.
