I'll prolly get flamed for this, but since I don't have experience with the mice you mentioned I was bored and I thought I'd throw my suggestion out there
I love the way the buttons are placed on my WoW Cataclysm mouse, wouldn't trade it for anything. 14 is plenty and the software is a piece of cake. I don't like all those "touchtone-phone-arranged" multi-button mice. And if you can't find the cataclysm one, the legendary one is pretty much just as good, just 3 less buttons but still enough.
If you do go this route, may I suggest creating custom "macros" for each profile in the software, even for WoW itself, heck especially for WoW itself. Just map key-bindings to each button. Most likely you'll do that with any mouse you get of course, but some ppl get wrapped up in the "Oh this button just automatically opens my bag" stuff..lol...what a waste when they could optimize their combat better!!! Good luck in choosing one, hope you get one you like.
