Fedora. Regular releases and they're typically the first to adopt new technologies. I used to run Ubuntu but they have a terrible case of rolling their own tech that they put under a CLA or leave significant parts proprietary, like Snap/Mir/Unity. I started with Debian back in ~2002, which I still love but I prefer Fedora's release cycle.
