i was lucky enough this year to be able to taste: bombay morich, assam bhut(indian carbon) and the dorset naga.
while the morich & assam had similar heat and very similar taste, the dorset naga had the best flavour and more heat. now, the morich & assam were the first peppers off the plants and were quite small, as more larger pods start to ripen on the plants perhaps that will give me a better comparison. i did my taste tests all within a half hour so i could remember the flavours. all seeds came from pepperlover.
good luck.
