The Flying Goose brand is the most common here in Germany. The Huy Fong brand hasn't been available for a few years after the EU implemented some restriction on one of the ingredients.
It's also the only acceptable. I've tried every available other 'knock-off', too. They were bad. No matter if green, or red capped. I guess they were too old, and have gone bad on the shelf. Realized that much later, when I had a small, almost empty bottle of the Flying Goose stuff, and the last of it tasted bad the same way the others did. Also smell, nothing strong, but noticable, once you know it. I don't know how to put this exactly. An 'empty' sting? Feeling hot and sharp, without being spicy? More like tear-gas? Just numbing without taste?

My fride, my pantry and my local Asian shops would respectfully disagree with that statement.
Hui Fong Sriracha is less sweet, less garlicky, brighter and the chillies come out way more. It's not the same product as the Flying Goose brand and they certainly can't be substituted for each other. I love 'em both.
