Presentational is definitely the best way to watch a play. The Comedy of Errors especially is better since it was written as a comedy. Presentational works the best with comedic works because it really amps up the comedy and sillyness. The whole idea of the play, twins meeting and mistaking one another for the other one, is so absurd, that if the actors played it representational, it would not keep the audiences' attention. For me, Shakespeare is more approachable when it's funny and it almost seems easier to understand that way. Presentational plays engage the audience and keep them interested in the story that, to many people nowadays, seems archaic and unrelateable.
