The concesus is definitely paladin. After tanking with a warrior for a while I decided to roll up a pally tank and abandoned him at lvl 30ish and I found it a lot more of a pain in the butt than tanking with a warrior. So once you get used to one kind of tank, I think that class will seem "easier" for you. I've tried druid too which I stopped at lvl 68. I found druid to be very very similar to warrior and it was a blast but I just didn't want to keep paying for the extra account.
