Hmm on the one hand Baileys is ever so delicious and tastes good in coffee, hot cocoa, and milk. I actually really don't like alcohol much at all and besides a wine or two and Baileys there's only a single hard liquor I could drink. That would be Drambuie. So my favorite pure liquor is Drambuie and favorite thing to add to other drinks is Baileys Irish Cream.
Drambuie cuts it close as it has such a great story and legend behind it. Plus it's sweet, spicy, smooth, and really is a great sipping drink.
