I would chose to side with Protopiro opposed to Didascalo (who voices Piranesi). I like how Protopiro is strongly oriented with Classical Greek Architecture and I believe this is the basis point to extend all other architectural details. I like to see the structure and recognize the commonalities just as Protopiro does. In contrast, while Didascalo does agree with a more ornamented style, I believe there needs to be a basis point before moving onto the ornate details. If I made a standpoint, I would agree with something that is a combination between Didascalo and Protopiro.
