If you could only have one mount...

[countdown]

I find the Headless Horseman's mount to be the best for both flying and ground work. It doesn't make any noise, doesn't fill up your screens, and fits through doorways.

[Ualaa]

I don't have Ashes of Alar, but think that would be a great mount to have if you could have anything but only one.

The Vial of the Sands is good.
If it were a non-flying ground mount, when you could not fly, that would be better... if you were restricted to a single mount.

Although there's no way to tell that it was my intention, I was really thinking about which mount peeps would choose in BGs (flying doesn't matter, having a huge target on your head because of 5 massive mounts needs to be taken into consideration).

[countdown]

I'd say any of the standard mounts, like rams, horses, etc. Something that doesn't scream "target me".

[Ualaa]

I generally use the War Bears, in battleground pvp.
Sometimes the Frostwolf Howler.

They're both PvP rewards.
And neither is obnoxious, like some of the purchased mounts.

Basic PVP mounts - frostwolf howlers, war mounts (pvp reward ones). For flyers I use the original swift bats. To my faction I feel it's rude, if not griefing, to run around on grand war mammoths or proto drakes covering up stuff and getting peoples' way, or mounting 5x war mammoths in EoTS or something. And I have no interest in attracting even More attention from the enemy faction. People already know you're multiboxing, no reason to be obnoxious and take up half a town.

hard to say, as I have now 215 lol, just got Onyxian Mount, bang on the 100th Kill, well my daughter got it, on samebnet as my accounts, we both farmed it, she more then myself, I love Ashes, for its unique look, and how it stands out. Its still my fav and most used flyer.

Ground mount, I prefer my spectral or the black panther I use from ZG, just looks awesome, being a hunter and on the black panther, dunno seems to go together.

Minrons heads be great, but overall Id love one of the arena mounts, thats truely rare, but since I never will have such skills to ever get one, its Ashes, Ony, Spectral Tiger + Black Panther mounts. Cant really select one, as I like those 4, and sometimes my kara mount. lol

Tho my boxers use the JC mounts as its easier for ground + flying in the one mount

Flying? Alar or mimron's head
