If you are just going to stay recreational skiing and all the other water sports go with the Nautique VDrive. The extra space is great and much more family friendly.
If want to go hard on slalom cannot beet the Prostar especially at longer lines slow speeds. The Malibu Response with a Wedge is another option, a great family boat that you can actually surf behind with little added weight and still great slalom wakes. Response is similar in size to the Prostar though so not as good for space as the Vdrive.
I have a Prostar and love it, my younger kids wish I had a surf boat.
