Udyr covers all the bases, having great ganks with a stun/movement speed boost, fairly low mana reliance and good self heals and in theory at least the fastest possible jungle clear time, by a factor of about 12 seconds, on top of very little item reliance as well as being a counter to the popular Amumu, the trade off being that he drops off HARD late game.
