Red meat would have to be lamb (shoulder is the best), which you have inexplicably left out, otherwise chicken as it is versatile and reasonably cheap compared to other meats - Free Range ONLY.
I love seafood (fish is okay, prefer crustaceans), but I wouldn't consider that meat as such.
Beef - rump (rare) has the best flavour, but tends to be tougher than other steak.
Venison - can be dry as there is little fat.
Game (I assume you mean birds) - watch out for the shot, but very tasty - again can be dry if not cooked reasonably rare.
Pork - ribs are my favourite here, with a nice sticky, spicy hot BBQ sauce.
I have not tried human, except the odd lick on a live one, but am lead to believe that the flavour is not unlike pork.
Ostrich steak is pretty good - quite like beef.
