Another user mentioned a handful of benefits. I would add that Fedora is more secure than Ubuntu or any of the derivatives you mentioned out of the box. In fact, it’s more secure than most other regular Linux distros.

I also like that it uses vanilla versions of Gnome and KDE. They leave the customization to the end user.

Speaking of KDE, if you prefer it, there are few distros that do it better. Maybe OpenSUSE Tubleweed or Open Mandriva ROME. For me, Fedora KDE Plasma fits my needs almost perfectly.

Finally, I think the installer is way better. Ubuntu’s has become less flexible over the years. Fedora’s is still super easy but offers a lot more options.

The one potential drawback I can think of is that official versions of some software are only available as a .deb. That’s more and more rare in my experience.
