I’ve had a couple spicy shark ones that have flavour. They also have the pure extract ones but I usually stay away from those
There’s a Korean BBQ hot sauce that I think is really good
There’s a matouks west Indian hot sauce I’ve enjoyed
I’ve found that hot sauces that are a bit chunkier and have actual ingredients like small chunks of chilli or pineapple tend to have a more balanced flavor and heat profile though
