SUSE has a lot of ex-Red Hatters at high levels these days. Their CEO ran Asia-Pacific for a long time and North America commercial sales for a shorter period.

SUSE has always been pretty big in Europe but never was that prominent in North America except for IBM mainframes, which Red Hat chipped away at over time. (For a period, SUSE supported some mainframe features that Red Hat didn't--probably in part because some Red Hat engineering leadership was at least privately dismissive of the whole idea of running Linux on mainframes.)
