RHEL software is often a little bit dusty. Updates to more actual
software are done very rarely.
One thing I really hate on Red Hat is that they often use a patched gcc
so several Red Hat packages don't compile with a standard gcc.
The update support for RHEL is now 10 years (extending to 13 years is
possible, but expensive).

CentOS: It is not RHEL. It is build from the source packages of RHEL,
but is is a community project with no direct relation to Red Hat. Since
this year Red Hat and CentOS are working more close together.
http://lists.centos.org/pipermail/centos-announce/2014-January/020100.html

Suse Enterprise Linux: The distribution for number cruchers. For Novell
and SAP applications SLES is the first choice. Update Support is 10
years. Suse and IBM are collaborating since now 20 years optimizing
Linux on IBM hardware. On IBM Power systems SLES is the best performing
distribution.
The OS for machines like this: http://top500.org/system/177975 (only the
electricity bill - without AC is over 30000$/day) or this
http://top500.org/system/177719 is SLES

Other than Red Hat Suse does not release source packages you can build a
running system from like CentOS from the RHEL source packages.

RHEL and SLES having a 4 years window for enhancement requests. After
this time they are not releasing updates to newer versions except a
security update makes it necessary. If you compile your own versions
this is not covered by the service contract you buy with this distributions.

Debian their release policy is: It is finished when it is finished.
Debian is the distribution with the shortest reaction time on security
fixes. And a rock solid distribution. Stability has a clear priority to
actuality.
Update support is stopped one year after the next stable release.
Since Debian is a 100% community project no direct commercial support
available. Third parties offering this.

Ubuntu is based on Debian and mostly using more actual software than
Debian. The real priority of Ubuntu is the desktop. Several details are
also different like the init system.
Every two years the April release has an extended support of five years.
Commercial support is available from Canonical.

And don't forget BSD.
