And that's why there are so many different brands. La Choy, if I remember correclty, is made from hydrolized vegetable protien, while Kikoman is made by brewing soy beans. Kikoman makes a true soy sauce.
As you said, the flavors are profoundly different. You prefer the La Choy, while I love the Kidoman. And that's perfect. All of us react to different flavors in different ways. I am happy that you have found a soy sauce that you really like. And I'm glad I've found a readily available soy sauce that I really like. It keeps both companies going.
