I also like the promise especially in the 2 pump version. I sell both caldera and marquis. Promise and Martinique are 2 very different tubs. The Martinique has a lounger whereas the promise is more open multi level seating. The 2 pump promise will be more powerful and have a full bottom pan bottom as well as more jets. The Martinique is also a fine tub. Not as powerful as the 2 pump promise which good be a good thing or a bad thing depending on the consumer. Martinique has nicer standard lighting and a circulation pump. Both will be very energy efficient are both great tubs. The promise will probably be about 1,000 dollars or so more In the 2 pump version but it has a nicer overall finish and a more heavy duty cabinet. Either way both of these tubs are nice tubs. Wet test and figure out which tub works better for you. Personally I like the more powerful jets the promise has to offer and I like the fact that both pumps are dual speed but I would let the wet test be the biggest factor
