Welcome to our forum.
I will try to be as unbiased as possible and explain some differences.1.) Marquis has a high flow system, a circulation pump is a low flow system. Marquis used to use a circ. pump, but found it more effective to use the jet pumps to filter the water. When you use jet pumps you are able to churn up a lot of water and actually get movement on the surface. The surface is the dirtiest part of the water, so doesn't it make sense to skim the whole surface area? On the Jacuzzi if you watch the circulation pump it is basically trickling water out of the spa... you will not see much surface movement at all. That means if there is hair or debris floating on the surface, it is unlikely to be filtered out. Marquis is able to filter more gallons of water in just 4 hours of the day, than the Jacuzzi can in 24. The circulation pump was also Marquis' number one warranteed item when it was put in our spa. Think of your car, could it run 24 hours a day, 7 days a week, 365 days a year and not fail? 2.) Marquis solid state ozonator requires no maintenance and has an average life of 5-7 years. Corona discharge ozonators typically have to have yearly maintenance. 3.) The HK40 has no 90 degree turn in the back of it, allowing it to put out 40 gallons per minute. Even the large HK16 jets in the Epic don't come close as far as water output. The looks of a jet face can be decieving. Be sure not to mistake pressure as being stronger. Marquis believes in high flow, low pressure, allowing for deep tissue massage.4.) You will have to be the judge as to which manufacturer is superior. Jacuzzi is a respectable brand. I will point out one HUGE thing- warranty. Marquis has the only transferrable warranty in the industry. You will also not find exclusions such as water chemistry in the Marquis owner's protection plan.Good luck, it's obvious I sell Marquis, but like most other Marquis salespeople, I passionately believe in the product.

This also means that your ozone system is only working 4 hours out of 24. In my unbiased opinion.
Here is a Jacuzzi dealer reccomending 2 year and 3 year maintenance on CD ozonators:http://cdabilliards.com/spas/spa-maintenance/Sorry, their website is giving a biased opinion
