Hard to say because it depends on moments and seasons, seasoned straight rum in general.
Appleton Estate 21 (if I have a drink 90% is AE 21, my n°1 is AE 30 but it is hard to source, limited production I only had 1 bottle so far, much deeper than anything else I tried), Vizcaya VXOP Cask 21, Zacapa Centenario XO SGRE or Don Q Gran Añejo for rum.
Otherwise scotch or irish Whiskey HP 25 (great), Glenlivet 21, Macallan Cask, Collins, Jameson, Black Bush, JD cheap and really not bad or even an interesting Lark DS I enjoyed lately visiting SE Australia.
Italian Filo e Ferru rough and uber strong (50°-60° even if I aint a big grappa person) but very interesting.
Sry for the long list, I really had to mention a few.
