For me, if I was stuck and felt they were basically the same, I would make my choice based on support. Such as this site for example. The people here are nice, willing to help, and go out of their way in may cases to do so. If you can find a place like this for the Yamaha, then we are back to a tie situation. For me, it will always be a Seadoo as I feel I know them pretty well and because of this site.
