Both great tubs! I happen to sell them but IMHO the Bahia is about the best "bang for your buck" out there. Is the Moto-Massage and the "no bypass filtration" worth the extra 2-3 grand to you? These are both unique to the HS and definitely worthwhile. Beyond that the tubs both are full foamed, both have 24 hr circulation pumps, both have 5 yr parts and labor on their warranties. You cant go wrong either way! I say WET TEST and see which fits you better, has the most power, etc.
Good Luck
