Since Poison type is now going to get a surge of popularity in Gen 6, I can't consider it my favourite at this point forward now that the tasteless masses will start to call it their favourite type as well.

As a person of discerning taste, I now need a new favourite typing.
So, which typing is going to be the obscure, forgotten, and esoteric choice that I can appreciate while the feeble masses are drawn to the popular, tasteless ones? Will it be Rock, or Bug perhaps?
