I have to admit, even though I still find melee classes boring, I have been enjoying the barbarian because of the dialogues.
From what I've tried, there are even small differences between the intimidation options: berserkers is more "raaagh" and gets advantage on these checks.
Unfortunately, 5e is pretty boring by the standards of earlier D&D versions, and 5e martial classes are particularly dull mechanically. But, like you, I have enjoyed the dialog and skill interactions of my pint-sized bundle of halfling/bear fury
, maybe even enough to choose the class for my first release playthrough.
