You can argue this all day long but what you cannot argue is a Marstrom platform has never won the A-Class WC and a wave piercer design has won it every year since 2000.

I think Marstrom has some valid points but I also think designers like Pete Melvin are convinced the concept works when it is applied correctly. I've owned three wave piercing designs and I believe the pitching is reduced upwind. Downwind, there is a technique to pushing a wave piercing boat hard but the introduction of curved daggerboards has made it easier.
