Thanks, in our case we would be an enterprise "buyer", so support
shouldn't be an issue (in theory) <g>.

On zSeries, RH was a latecomer to the game (by almost a year), and
sacrificed the installation momentum advantage to SuSE in terms of
number of installed copies and vendor certification. That advantage has
continued to widen, courtesy of a lot of poor marketing by RH (to the
point of RH salesvermin telling customers not to use RHEL on Z but buy
Intel instead), and slow certification of popular middleware.

In our testing, both are comparably stable, but have problems in
different areas (for SuSE, primarily in the installer, and for RH,
differing locations for common files from the LSB and finding anyone in
their support org competent to handle questions on non-Intel platforms).
RH also has a very restrictive support policy for instances on zSeries
that makes non-enterprise customers choke compared to the liberal
support policy provided by SuSE/Novell.

In general, companies that already have significant relationships with
RH appear to be the major population of RHEL users on Z due to expanding
the existing enterprise support contracts being easier than dealing with
a new vendor. SuSE has consistently been faster to the mark and shown
more commitment to the platform, and is usually the first of the two
major commercial distributions to deploy new Z-specific features (Debian
and Slackware often beat both).
