As said above, if it's just for a pet, than I'd just get the regular Mojo. No need to spend the extra dollars for something you wouldn't use. Of course if there's a pattern that you love out of the three, get that one! I've picked pattern over genes.
I'm picky as well, and none of those stick out to me, I'm more of a sucker for crazy side patterns (You should check out my new Mojo girl's thread, she's got some cool side markings). Just get what makes you happy!
Just be aware that if you do plan you breed with any of the het Mojos, you'll have to get another het for that gene or a visual.
