After having tried many distros, I settled on Fedora. It's a boring choice, but it has been a great experience for me. Everything pretty much works without issue, and the OS gets out of the way for me to do my work.
I also think that having a trustworthy company and team behind it matters. It's hard to trust some obscure distro to provide proper support, security updates, and proper testing.
Also, while I enjoy tinkering and messing around, my main OS is not one of the thinks I would want to tinker with. I have work to do, and I need a stable platform i can rely on.
