My boyfriend is soon celebrating his 30th birthday and I'd like to surprise him with a bottle of good whisky because he loves it.. But I don't have a clue what should I choose

So far I have had a exact orders from him ( Bruichladdich sherry classic, Laphroiag triple wood, Jura Superstition, Caol Ila 10y).. Does these tell you something on his taste? What on earth should I choose to him,please, I'm helpless!!
