need help with a boat decision

I am about to buy a used boat and I would like to hear your opinions on which one I should go for. Here are the two boats I am considering. 1998 Malibu Sunsetter LX, 287 hours, clean interior and exterior, monsoon engine, wedge, fly high pole with speakers and racks. The other one is a 1997 Sport Nautique, 600 hours, Monster Tower and Racks, Perfect Pass, new interior speakers. Interior and exterior not in great shape. Both are priced exactly the same and I will use it only for wakeboarding and wakesurfing. Let me know what you think as far as wake, reliability, resale value, etc...
Thanks in advance.
