Not a big Busnel fan. My preferences tend toward Dupont (which is a brand I now represent but I have liked it for decades) and Christian Droin.
I have a couple of bottles of single year Drouin calvados and they are superb. Prices seem to have gone a bit nuts but the 1977 I have is really really good.
I’ve never tried/had any calvados. But, whenever I hear the word I think of this catchy Golden Earring tune:

To be fair, it sounds as if all couldn’t be blamed on the drink . . . .
