Fyi, both of those are made by the same company. I'm personally not a big fan of thermospa. They are way overpriced for what you get. The profit margins on them are significantly higher than the rest of the industry. It's all marketing b.s.
I would look at the Bullfrog R5L/A5L/X5L, the Artesian Santa Cruz or their South Seas 532L. The Marquis Spirit. Dimension One Triad. HotSpring Jetsetter.
Those are all really great small spas, as is the Jacuzzi. Skip the Thermospa.
