We’ve done all 3 and I’d say Epic/Getaway/Breakaway in that order. We like the Getaway ship overall more, but the Epic Haven really is the largest of the 3 with more space in the restaurant and lounge areas. More sun deck and pool space. And the rooms are recently updated so you don’t have the “weird bathrooms” people complain about on the rest of the ship, even if you are not in the haven proper.
