As a fanatic fish eater I would have to say that the answer is in the taste buds of the eater coupled with where the fish lived and how the angler handled the fish. My taste buds tell me that a fish with pink or reddish meat usually has a better flavor than a white meated fish provided it has not developed a mossy taste. Most brookies have colored meat while rainblows in a stream usually are white meated. Red meated rainbows are great tasting.

Best thing you can do is a teste test. I usually roll trout in seasoned (salt & pepper) flour and fry. Panfish I usually fillet and fry in Panko crumbs.
