"In conclusion, it is up to you to decide which distribution
best fits the system you need. I prefer the free distributions as I
end up finding free support on forums, which include Fedora and
CentOS. For workstations, I prefer Fedora as it provides the
cutting edge software and tools. For servers, I prefer CentOS
because it provides rock solid stability and a long lifecycle per
release of RHEL. As always with GNU/Linux, you can download and try
the free distributions and give them a test run.
