Favorite and least favorite Hearthstone heroes

Greetings, DayKnights! If you're playing the Hearthstone beta, I want to know which characters you like to play, and which ones you don't, and why. Do you love board clearing with the Mage or Druid? Do you prefer annoying your opponent to death with the Priest or Rogue? 

Personally, I find some of them quite intutitive, while I absolutely do not understand how to play others. I want to find out if other people feel the same way.
