Trying to decide between style, Toto Promenade and the Drake. If we were to go with the Promendade, then we would also have to consider the Kohler Memoirs (one piece) because that would match the sink we are using. We're have a tough time with the choice - Anyone choose to rate the 3 toilets on a scale of 1 to 10? Or other suggestions, differences, problems or successes.
