We had exactly the same problem. We thought we wanted the sovereign then wet tested it and found out we did not want the lounge. We ended up buying the vanguard (after wet testing it) The Vanguard is deeper and has the motomassage DX in addition to the motomassage (the DX has 2 streams compared to one with the standard motomassage) The jets may feel similar between the two, but I would recommend a wet test of the vanguard if at all possible. You can get a feel for wet seating comfort, "floating" tendancy and overall room and geometry. (IMHO, these were more difficult to obtain in a dry test) My wife and I both wet tested all of the tubs we looked at and were able to get a feel for the "geometry" and room in the tub when we were both in. Anyway.. my $.02...
