Sure, Tailhooker.
#1 (For both me and my wife) was the Epic.
#2 for me was Jacuzzi J480
#2 for my wife was HS Grandee
Flip-flop the above two for our #3's.
Those were obvious to us. After that, it's hard to say. No tub "wowed" me. Talked to some nice dealers, though. 1,2 & 3 were all about how the tubs felt to us when we wet tested. I needed good neck jets. My wife likes variety of therapy and foot jets.
If forced to, I'd probably say I liked Artesian #4 -- Tested Grand Bahama & Piper Glen. PG was a gorgeous tub and I liked the idea of a separate pump for each seat. But I gotta' say -- for a lot less money, the Island Series Grand Bahama was right up there with the therapy. I didn't care for the lounger, so I would have gone Grand Cayman if I was going to buy.
Sundance Maxxus & Optima #5. Although, my wife hated them -- said the jets stung her -- even turned down.
Caldera #6 -- I think we tested the Tahitian.
Probably D1 #7. We wet tested a Chairman II & Amore' Bay. Didn't like the diverters on the CH2 -- very hard to turn while the pumps were on -- but the dynamic sequencer was kinda' cool. Liked the 2 captains' chairs on the Amore' Bay -- cool water features, but the barrier free part of the tub was lame, I thought. Cool party tub, though. And very pretty.
Last, I'd say Cal Spa -- can't remember what model I tested, but it was back-to-back with the Jacuzzi & Sundance, and didn't feel in the same league at all.
Hope that helps!
