Instinctively I find underlining for emphasis distracting and much prefer bold or italic. From my research it seems underlining is a carryover from typewriters that were incapable of italicizing or bolding.
I'm currently in a situation creating written content with others who love underlining as a point of emphasis and see nothing wrong with it. They sometimes include italic and bold in the same paragraph.
Should I try and break the teams underlining-for-emphasis habits or change my perspective on it's appropriateness?
