The original Amani War Bear, also I'm a big fan of protodrakes: the ulduar 25 protdrake has the best color combination imo. I use the timelost one tho - my favorite. rare, more rare, timelost (alot of time lost :/)!
My favourites are the Pureblood and T14 Meta (Heavenly I think it's called from the top of my head). I pretty much only use the heavenly now though, I like to feel like a special snowflake - even if only for a tier or so

You can use the disgusting OOzeling and turn it green! Although, only while grounded But still, Green!
I'm a fan of the thundering cloud serpent, though the frost wyrms have always been a favorite as well. For ground mounts, I like the spectral wolf a lot, as well as the sunreaver hawkstrider (on my blood elf at least).
(Rareness does not affect how much I like something, and I cannot comprehend the concept of personally liking something more because it's rare. )
Those two are definitely in the top running. My favorite mount overall is Invincible, even though i don't have one yet QQ. The most unique overall I'd say is Mim's head because it just looks all sorts of awkward lol.
