I've been using Fedora for the last 7-8 years, but I have to upgrade every 13-14 months or so. And CentOS is not suited for a modern development/workstation environment.
Why is Ubuntu the defacto supported Linux distro? Why is,quite often, steam so difficult to install, while it's a breeze to install on Ubuntu?
You can't expect people to consider you as a legitimate target if you're constantly moving :(
I can't say bad things about it, except that it's quite often that you can't find packages for various applications. A random example would be spotify, that was one of my last adventures to make it work(I got tired and gave up after a while).
And Fedora/RH has a lot more momentum in general and you can be certain that it will be around for as long as Linux is a thing I guess :)
Suse has gone through various struggles and it doesn't inspire much confidence to me anymore.
