In my opinion and experience:
Sanger is the best quality of the bunch.
I checked them out a bit. They have limited space, due to the design.
The design, though, gives it the best wake of the three above.....
So, IMO, for quality and wake, go for sanger.
Off the other two, roll the dice if you want more interior space (totally my opinion based on what I have read here).
I seriously considered Sanger a while back. The new boats ended up being more money than I thought, and had less interior space than I was willing to settle for. I bought a used boat instead of new.
Hope this helps.....
