Some say "which one is better?". This is my opinion and suggestion. There are base on Red Hat Linux. For my experience its easy to get the purpose or objective for this Linux to be implement. More peoples and websites suggesting the server purpose to be using by CentOS because it is an enterprise level OS based on Red Hat and for Fedora it is mostly for testing bed and more on user Desktop purpose. Fedora is bleeding edge and potentially unstable by design. For this reason, now you can easily define what is the best choice for you desktop or server.
