Which is the more exotic Druid race?

[Aalderon Crystafire]

Human and Half Elven druids are both quite rare. I've personally come across more humans than half elves but when I've regularly checked / all hum druid and / all half druid they are usually about equal.

What do you think is more exotic? Humans allow for robed druids but at the same time humans can be seen as any number of casters - Enc, Mag, Wiz, Nec. On the other hand you're never going to see half elven casters (outside of some odd bandits) and the half elf druid allows for this.
