Opinion on WoW Dragonflight/Drake point, go!

Which do you think is the most intelligent of the dragonflights/dragon types listed below (for RP/story purposes):

Netherwing
Proto Drake (specifically the green one - OMG I GOT MINE LAST NIGHT!!!!)
Red Dragonflight
Bronze Dragonflight

Reason: I am attempting to pick WHICH drake Arlu will consider her "companion" mount and, well, I *do* have 60+ mounts...

Edit: Oh my god, the "bouncy" image looks like an insane maniac! HAHAH *loves*
