Does the pi run pretty quickly when running pidora, or is it below par? Par being raspbian on the pi zero.
As Ghanima points out, they are almost certainly on par, since the basic components are all the same (especially now that Raspbian uses systemd). The kernel used in both cases is exactly the same.
There is an important caveat about Pidora, however -- it is no longer being maintained. I've been using it for a few years (Fedora is my preferred linux distro) on a B then a B+, but it has been a long, long time since
yum upgrade said anything but "No packages marked for update." I am planning on replacing that install with Raspbian soon. The pidora homepage is last dated 2014; I know it was created by a university research group, meaning not-really-volunteers, and when not-really-volunteers stop being paid or receiving academic credits they tend to move on. The Pi Foundation stopped listing Pidora on its pages a while ago.
So while it does work and there is nothing wrong with it besides this, I strongly encourage you not to bother.
