Fedora is much more secure (a strong focus on SELinux, secure boot, etc.). Fedora has more cutting edge software (latest GNOME, gcc, etc.) while still being very stable.

A large chunk of the gcc/glibc/GNOME/Wayland/... developers are employed by Red Hat and Fedora shows that, it's where the Linux workstation is going and has an amazingly good of integration of new tech. Most other mainstream distributions trail by several years.
