I sold Jacuzzi for 16 years, the 50/50 air ratio is only on the 3 power pro jets, still a nice spa though. The pulse no idea I am sure it's fine. We switched to BF 3 years ago and have been really happy with them and the company support from them, they really do stand behind their product and their dealers which is whom takes care of you.
Really comes down to what works for you, I do like the 2ea 2spd pumps in the BF no one really offers that anymore that I am aware of. The jet packs give you even more flexibility for what you might be looking for hydrotherapy wise, least if you like a certain jet pack you can move it to the seat of your choice like a shallower seat instead of a deeper one if you are vertically challenged.
