Personally, I'd stay away from LA Spas in general. I've not seen them to have good quality. While they may look flashy, everything I've ever heard has been that is where it ends for them.
But, if that is what you have your heart set on, then go for it.
As to whether or not to go for more jets, without wet testing the one with more jets, it is hard to say. Just because a spa has more jets, doesn't make it a better spa or mean it will give you better therapy. The jet number game was started by companies who had to put a lot of jets in their spas to compete.
One of the number one brands going got started and built their company with a spa that had four jets. They grew because they become known for quality.
