questions like this get people all riled up on Wakeworld for some reason... well because it's a this vs. that and instead of just stating the positives people tend to just talk smack on the boat they don't like.
YOu may get some good responses here but if you don't then my suggestion is to listen to Art above
if not, you might want to check themalibucrew.com for what people like/dislike about the vlx and tmcowners.com for what people like/dislike about the x2.
I've been in both and PERSONALLY (ok everyone) did not like the wake of the X2 but loved everything else about it. The bow is incredibly roomy. I currently have a VLX and my PERSONAL opinion is the fit and finish of the X2 was better (not by leaps and bounds or anything) but i like the stock wake on the VLX a lot better.
