Chocolate junkie. That's me.
Quantity over quality.
Having said that, sometimes I recognise quality. & when it comes to that, Swiss & Belgian chocolate brands are probably the best.
When in Germany, I usually eat mostly Alpia, which IMO has the best value for the price. (Usually bought it on special offer between 30 & 50 Euro cent per 100g. Don't know how much it costs nowadays.)
Here in Greece I usually go for the Lidl own brands, which are luckily in recent weeks often on offer between 40 & 60 cents.
&, of course, I prefer the sweet stuff: noisette or nougat.
(Never tried East European chocolate, but several Chinese brands: they generally suck.)
