So you attach a picture of a clam shell, rocks, and some sauce? None of that looks like fish to me. To your points, tastes better - that's subjective, but I like the whole variety of meat flavors, including many fish. Looks better? Again, subjective, and culturally biased. Way healthier? Debatable. Very dependent on the fish. Most (not all) fish aren't fatty enough for human nutritional needs. Also somewhat dependent on the diet of the fish, for both flavor and nutrition.

My primary diet is beef-based, but will eat salmon and dungeness crab whenever the opportunity presents itself. It is rare that I go more than a month without having one or the other. (Crab is lean, but lots of melted butter helps.)
