Had some Green & Blacks Chili chocolate yesterday, didn't think much of it. Chili shouldn't be a chocolate flavour imo.
It's interesting how your taste buds adapt over time.
A few years ago Cadburys Bournville tasted bitter to me, now its far too sweet.
I do love some nice dark chocolate though 75% is good. Goes a bit to bitter after that. If you shop in Aldi I can recommend the Mosher Roth stuff, handy as it comes in individually wrapped bars
