This question is a bit like asking how you like your meat being cooked.
Some people prefer cloudy, others milky and some others amber.
THC turns into CBN (not CBD) by his natural oxydation, trichomes cloudy and milky are THC before its oxydation and turns amber into CBN.
THC makes you feel High, CBN makes you feel Stoned. Now it depends how you wanna feel 😊
