I had the same prejudice about Fedora and RedHat back when I was a debian fanboy. But if you look at what Redhat is doing with their money and their company then you soon realize that Redhat Inc. not only IS a large part of the Linux community, but also supports the open source movement in many ways.
So Fedora has been my main distro of choice for a couple years now. I still hesitate to order RHEL licenses at work, unless the client specifically has a good argument for choosing RHEL I tend to lean them towards CentOS.
And I can speak from 12 years of professional sysadmin experience in BSD and Linux that yum or dnf is a very stable package manager.
I've had more issues on Debian 6,7,8 than I've ever had on CentOS or Fedora.
