We have had our Bullfrog 451 for about a year and a half, and we love it. No problems with the tub at all!. You would do just fine with either tub, Hot Springs makes a very good product but I'm a little partial to Bullfrog. One of the nicest things about Bullfrog is the ability to customize the jetpacks to your liking. I am just a tub owner not a dealer but I'll do my best if you have any questions.
