The CP rear seats ARE like two large patio cushions, with bases actually, so yes not nice for cozy evening cruises but I like them for ease of use and removal. All the boats are so darn good now, I love the CP yet wouldn't turn down the the other three, BUT not willing to give up another $25K for them! (Also not sure MC is the only one with innovations but they do have a few very slick ones)
Back to the point of the post, from all reports the MC has stellar lower speed 'learning' wakes. (As does the CP) but the SN isn't far behind, the Malibu just a bit behind the other three but more room and storage for the family. Good luck in your quest. (Maybe choose the one the wife and kids like best! haha)
