I grew up on kikkoman, view it as the soy sauce equivalent of Heinz ketchup or Best Foods/Hellmans mayonnaise and still cook with it all the time. But after tasting a wide variety of soy sauce I would describe kikkoman's profile as salty, metallic and stout-beer like. The fancier soy sauces seem less salty (despite similar amounts of sodium) and can have varying notes of oyster sauce, seafood, sweetness, coffee, molasses and MSG.
