This 6.3 stuff is like science fiction. In particular, this bit from the release notes: A number of patches have been applied to the kernel in Red Hat Enterprise Linux 6.3 to improve overall performance and reduce boot time on extremely large systems (patches were tested on a system with 2048 cores and 16 TB of memory).

I see a lot of companies just sticking with RHEL 5.x because it just works and there isn't any significant functionality missing.

If you're using virtualization, then RHEL 6 is a massive improvement on RHEL 5 (and RHEL 7 will be another huge step forward).

Well to be fair I'm not so much involved in libvirt. But libguestfs had a massive upgrade in functionality in RHEL 6.3. The release notes cover all the changes between old 1.8 and new 1.16:
