There is fantastic chocolate made being elsewhere. Lindt is good, but mass-market, not the benchmark.
I love Taza chocolate from America, for example. The non-conche one. Its crystalline texture is really nice.
Similarly Belgian chocolate (https://en.wikipedia.org/wiki/Belgian_chocolate) has also developed into a brand.
Poor chocolate is made by replacing some, if not all, of the real ingredients with cheaper substitutes.
Read the ingredients list on the back of the packet and learn what's in the good stuff and what's in the bad stuff. Then buy accordingly.
