According to http://www.oracle.com/us/technologies/027614.pdf Oracle Database is #1 on Linux with more than 82% market share. Since Oracle Database under Linux is only supported on Red Hat Enterprise Linux, Oracle Linux and Suse, and since Oracle Linux beside the UEK kernel is the same binary and source as RHEL, the choice should not be very difficult. I'd choose Oracle Linux.
And for what it's worth:
I imagine that since patches and errata are free for Oracle Linux since March 2012, there are probably a lot more people using Oracle Linux today than there were 2 years ago.

If you want to be good at something you have to enjoy what you are doing. More market share means more competition and probably having to deal with more wannabe experts. I cannot imagine that market share will help to be profitable or successful unless you can offer something for which there is demand. For instance, if you have an idea how to make a system foolproof and virus free once and for all, than MS Windows was probably your best target. ;-)

I am just assessing the market. Partially to know if I should consider training specifically for Oracle Linux, or another brand.
The other big distro is Debian. In my experience, this has a stronger presence in the desktop market (e.g. Ubunutu). We (our team) have 80+ RHEL based servers deployed. There are 100's more Linux servers in the corporate, and none of them are Debian based. And more of them are switching from RHEL to Oracle Linux due to cheaper support and maintenance, and the availability of Public Yum access when testing new servers and new deployments. Our team's previous RHEL support contract included RHEL Satellite Server - one of a few down here that actually had their own RHN server deployments. A very neat tool, but also expensive in comparison and restricted to requiring licenses to deploy (which pretty much rules out dynamic test server environments). Also one of the reasons that we did not renew maintenance and went Oracle Linux instead.
Hey, this came out today
