I've played around a bit in the early levels of GLD, MRD and DRK, and all 3 tanks have things about them I like, whether it be DRK's mana sustain, GLD's smooth damage intake, or Warrior's fantasy of running up and axe-ing someone in the face.

Can some tank mains try and weigh in on which of the 3 would be easiest to get adjusted to the tank role in FF XIV in particular?
