RHEL, SLES, and Ubuntu are all long-since derived from different distros (RHEL from RH, SLES from Slackware, Ubuntu from Debian) with no common heritage. RHEL and SLES both have heavy customization to their software stacks as well, so they're even divergent on a system organization level.

If either binary works on your system, use it, but I don't see a reason to choose one over the other based on similarity to Ubuntu.

Hello Folks,

IBM's ILOG CPLEX for x64 linux contains binaries built for 2 different
systems:

x86-64_rhel4.0_3.4
x86-64_sles9.0_3.3

Both of them seem to work on Ubuntu 9.10, but I'm wondering if either of
the systems are closer than the other to Ubuntu (Debian)?  If so, it
seems reasonable to use the binary built for the more similar base
system.

Thanks,
Daniel
