I have a 05 X-2 and have ridden in a SAN 210 many times. They are both great boats. The 210 wake is steeper and gives you quite a kick into the air. The boats are similar in that they are purpose built hard core boats. They don't have the interior space of some newer boats -- they are meant to take a crew out wakeboarding.
Actually, the X-2 (now X-1) is an excellent cross-over boat, too, for water skiing. Which is why I bought an X-2, since my son skis. Though my conversion of him to a boarder is progressing well.
The two boats at the top of my list are a SAN 210 and X-2/X-1. Not sure which order.
