A review of Fedora 22, published in ordinatechnic evaluates Fedora 22 as a good user experience and the reviewer recommends it for production systems.
Fedora 22, which replaced an existing installation of the Fedora 21 based Korora 21, has pleasantly surprised me. This is probably due to my terrible experience with Korora 20, aiming to make Fedora a friendly out-of-the-box experience. Although, at the time, I liked Korora's changes to Fedora, the bootloader installation was not reliable. In fact during kernel updates it completely wiped out the directories belonging to other OSes, including Microsoft's, in the EFI partition.
