Having owned both, I can say I would be perfectly happy with either boat. I like the seating and the big ass sunpad of the V drive, I like the storage and ease of maintenance on the D drive. jI honestly like both boats equally for different reasons. I recommend you get the cheapest one possible, I'd even look at the closed bow E21, they are great boats and huge for a closed bow. It depends on what you want to do with the boat, the wakeboard wake on all three is very similar. Not the same, but not significantly different. If you go out a couple or four times a week with four or five people, any of the boats will work great. If the ultimate wakeboard wake is all you are into, buy an Xstar and pay 200$ for gas every weekend;) If you ski, all three have a decent ski wake, the E21 is the best for that, the SX is best for WB wake just due to the fact that it has internal ballast, it handles best when loaded up. Wake size is about the same on a loaded out E22 vs an SX, the E22 is a bit more cupped and rampier than the SX. The SX wake is a little steeper with less of a cup or "sweet spot" like the E22 has. The E21 wake looks very similar to the e22, but I haven't been behind one loaded up.
