As I kid I equated fish with near tasteless (and what taste it had wasn't particularly pleasant) white fish in batter or breadcrumbs, which if they weren't too greasy, which was offputting in itself, was smiply not appetising; and so I declared I disliked fish. Tinned salmon being an exception, I really liked that.
But on reaching an age when I could go try things for myself I found there were many oily flavoursome fish well worth having. In fact I have two in my fridge as I write, one earmarked for dinner tonight, the other is going to try to stay fresh for tomorrow.
But I don't think it should be a contest between fish or fowl or any other sort of meat. Both fish and fowl are nice. And variety is the spice of life, or so I'm told.
