Keep in mind that the Wakesetter is a direct drive boat just like the Sunsetter LXi. The Wakesetter is probably the best value based on performance and versatility in the Malibu line.
Generalizing, I would say that if you spend more than 50% of your time skiing and you're comparing these two boats, get the LXi. If it's less than 50% get the Wakesetter and you'll be happy.
