Chairman Mao once said: You can't know the taste of plums until you have tasted them yourself.

Everyone's perception of food is different, and others can't judge for you.

But I personally prefer Ferriero Ferriero hazelnut wafer chocolate. What you said about Kym may be a high imitation of a domestic enterprise (no intention to belittle that company), and it's not too bad. It's just that Ferrero's taste is not crisp, and Ferrero's chocolate is not slippery or mellow.

Try it yourself. It is delicious.
