I've noticed this too. The Chip chocolate does seem different from other chocolates, eg, drumsticks which seem to taste more milky.
Chips are generally hit or miss for me. Gunther's quality overall is excellent. I have not really had a flavor I don't like. Favorites for me are coconut and lemon custard.
No they are not all that way each is different
I had the same thought with the espresso chip...
