It seems to me there are two aspects to the discussion.
1. ARE HIGH RIBS BENEFICAL TO MOST SHOOTERS?
Many of us would say yes they are, escpecially when shooting clay targets. For me, they help improve my sight picture, and I generally shoot sustained lead. Personally, I don't do as well with the traditional SxS "swamped rib."
2. GIVEN A HIGH RIB, IS SOLID OR VENILATED BETTER?
Clearly a personal choice and appearance issue. However, the venilated rib weighs less than a solid rib, which is a significant factor. I own guns with both types, and have a strong preference. The solid is more attractive in my opinion.
My old 1952 Browning A-5 has a high solid rib that I like, and shoot well. But I don't think Browning offers solid ribs on any/many of their new shotguns.
My new RBL has a low swamped rib, and thus far I shoot it poorly. Guess I need more practice.
