Starting again

I've recently switched from Xbox EU to PC/NA (thought it would be more populated on NA than PC EU) and now I am starting from complete scratch, I mainly used to play Battlegrounds using either Stam DK or Stamcro which I enjoyed them very much and now I am torn on which class to play between them both, and which would be better for grinding and doing general PVE content

I'm not exactly looking at minmax PVE build to do veteran dungeons just which ever would make the grind of levelling up easier and more fun any recommendations or advice would be greatly appreciated!
