LinuxBSDos.com published a review on Korora 19, code-named Bruce, which is based on Fedora 19
Korora is a Linux distribution that is based on Fedora. Korora 19, code-named Bruce, which is based on Fedora 19, was released the day after its parent distribution was released. That’s a little more or less than 24 hours after Fedora 19 was released.Korora 19 Review
Which means that the Korora developers did not conduct any testing of their own before making Bruce available for download. What that gives you are all the good features, bad features, and bugs that you’ll get by using Fedora 19 itself, plus some extras.
So what’s the difference between Korora 19 and Fedora 19? In one word, repositories, or repos. Those are the “extras.”
