The Nordic looks nice and is a good brand. Not sure about the other one.
The spa I liked in that price range was the South Seas Spa 748L Deluxe.
46 jets, 1-2 speed 2HP, 1-1 speed 3HP Pumps, Frog, Ozone, Pillow Fall LED and Dynastar LED. 3 Year warranty on surface, parts, electrical and labor, around $6,0000. It's made by Artesian Spas.
Good luck.
