The 6-month release cycle makes the most sense to me on desktop. Except during the times I choose to tinker with it at my own whim, I want my OS to stay out of my way and not feel like something I have to maintain and keep up with, so rolling (Arch, Tumbleweed) is too often. Wanting to use modern hardware and the current version of my DE makes a 2-year update cycle (Debian, Rocky) feel too slow.
That leaves Ubuntu, Fedora, and derivatives of both. I hate Snap and Ubuntu has been pushing it more and more in recent years, plus having packages that more closely resemble their upstream project is nice, so I use Fedora. I also like the way Fedora has rolling kernel updates but fixed release for most userspace, like the best of both worlds.
I use Debian stable on my home server. Slower update cycle makes a lot more sense there than on desktop.
For work and other purposes, I sometimes touch Ubuntu, RHEL, Arch, Fedora Atomic, and others, but I generally only use each when I need to.
