I have a 2004 X9 and considering your needs, which are similar to mine, it is a great all around boat. Wakeboarding is good, can make it surf, and for free skiing find the wake to be great especially 28 off or shorter, 30+ mph. Concerning how it handles open water it actually handles well and you do need to watch the bow at very slow speeds (less than 6 mph) on a rough day otherwise you might take one over the bow. It is definitely better at handling the water than the 197 and Response. As far as the interior, you can easily get two in the observer seat and they offer an removable seat next to it to sit 3 to 4 in the observer position. In general has been a great boat for my family and living on a big lake.
