The best hot tub is going to come from a dealer that will be in your service area. Find out the dealers in your area, see which ones are reputable and then check out the various brands they carry. Sit in them dry to get a feel for them, then schedule a wet test. The feel of the jets and the ergonomics of the tub are paramount.
Once you have narrowed it down to a few, flesh out the differences and go from there.
Go by what you're able to purchase in your radius, and which dealers sell what, vs trying to zero in on a brand. The brand may not be available in your area, or its tubs may not feel comfortable to you.
Do the leg work. Find out what works for you. Then report back to this forum. Numerous brand experts here will help you winnow down the finalists at that point.
I hope this helps. Good luck moving forward.
