Apis Quotes
We have found the Black complexion or something relating to it whenever we have approached the origin of nations. The Alma Mater, the Goddess Multimammia, the founders of the Oracles, the Memnon of first idols, were always Black. Venus, Jupiter, Apollo, Bacchus, Hercules, Asteroth, Adonis, Horus, Apis, Osiris, and Amen: in short all the... deities were black. They remained as they were first... in very ancient times.

I happen to like the "feel" of OpenGL more, which isn't something I can explain well to those that aren't programmers, but I don't think it matters much at this point which API one chooses. More or less, you have feature parity between both APIs, both have made a handful of design mistakes, and both do a few things in slightly more pleasant ways than the other. Of course, the unforgivable thing about Direct3D is that it only works on Windows. If it was truly cross-platform, though, I wouldn't really object to using it. But since you write OpenGL almost everywhere, and Direct3D almost nowhere, it seems like a false choice to me.
