All design is a compromise. All design is an evolution of a previous design. Design is an iterative process, particularly yacht design. NOONE gets it correct straight out of the box, if they did there'd be no need to tuning. The best you can hope for is that the person paying for the product is "happy" with the purchase.

What is your definition of "better". Cheaper may be better...faster may be better...faster in light winds may be better...

As a designer, the question is way too vague.
