Hearthpwn

I have enough dust to finish crafting one of these two decks. A friend allowed me to play them for a while and I can't decide which one to craft. I'd like to know which one of these is more viable to ladder with especially at higher rank (R4 to Legend).

Playing against Quest Warrior makes me want to quit the game a lot more than playing against Taunt Druid, so that might be a good choice

If you can choose I would go with Taunt Druid - it has more balanced matchups overall and can close out matches quickly with a Oakheart or Hadronox/Naturalize on curve.

Playing against warrior really makes me wanna quit the game. But Taunt druid has an overall better performance w/r.

Choose wisely and you will find true pleasure in your gameplay Mister Almaterrador

Both very fun to play, I would suggest taunt druid, for the consistency of being able to pull the combo. 

Still the deck is very weak against the Geist and Hex/Polymorph, and combo deck (Quest rogue, Shundderwock)

On the other hand, Quest Warrior, is very satisfying to play, there is a lot of decision making, and you can built the deck with only the Quest as a legendary. The deck is playable since it's release, and I think will continue to see play. 

I'd go for Quest Warrior
