Your iron grip is slipping, you let non-Linuxers into the thread.
I primarily use Arch for anything Desktop-style use, Fedora & CentOS for servers. I like how Fedora handles its SELinux with a very strong, working config for all default packages. It's a bit of work to add others but I feel that something like SELinux is a great thing to know for general security and wish Arch would pick it up, but I'm not about to sacrifice my gaming and package library for it on a main desktop.
I've also been keeping an eye on Solus and some of the new 'Atomic' style distributions like Fedora Silverblue. The idea of having docker-like layered updates for _every_ system update is really neat, and being able to just reboot to an older layer to reverse an update no matter how bad the update is just feels like living in the future. Most of that stuff is still too new for me to go all-in on, but I really feel it's where the future of OSes should be heading.
