Reddit mentions of Lee Kum Kee Premium Dark Soy Sauce - 16.9 fl. Ounce

both are just condiments, so quality won't vary much. where do you get that kikkoman is frowned on - just because it's and Asian product marketed to Westerners?

anyway, I just buy what's typically sold at most Asian stores, like S&B Wasabi paste by the tube,

I use soy sauce in place of salt for my regular western cooking, so I prefer mostly dark varieties like,

And with ginger - again I use whatever is cheap (sugar free - keeps longer) at the Asian store like;

the point is you may be much better off visiting an area Asian market then buying online as the prices and fresh turnover may be better locally. it's all a matter of taste so experiment, don't just take people's word for it.
