I've tried it once and it was disgustingly sweet. I'm unsure if the praise is just a meme or it's another entry on the long list of typical german food I don't like despite living there.
Hela ketchup is just really fucking sweet for some reason. It is also one of the worse Gewürzketchups I had, the supermarket brands usually are way less sweet and have an actual difference in the flavour of their different products.
Feel free, I don't hold you accountable to my opinion! I'm 100% sure that there are things in my cuisine that you'd find absolutely disgusting. Different people, different tastes.
