well Jacuzzi owns Sundance so these 2 spas are so close in many ways (footprint, jet count, warranty, # of gallons, pumps, etc.) I would get a quote and wet test one or either if possible to give yourself a better idea of which way to lean...I'm guessing the Jacuzzi will be slightly more expensive but that doesn't necessarily mean it will be a better product so again gathering quotes, wet testing if possible, and gauging the competency of the dealer will help make your decision much easier.
