Nautique 230 vs. Tige Z3 vs. Malibu Mxz 24

I am planning on getting a new boat soon and these are the 3 we were looking at. I am looking at the 2012 Tige Z3, 2012 Nautique 230 or the 2013 MXZ. I mainly wakeboard and thats all I want to do. Wakesurf a little, but it isnt very important. Out of those 3 which would throw the biggest and best wake. Keep in mind that I would be using it in saltwater. I am mainly thinking the Nautique because of the Coastal Edition and the quality of Nautiques. Also because Nautiques are used at the Gravel Tour in Orlando and once I get a new boat I plan on competing a lot there. What are your thoughts?
