Best bourbon?

Slightly sweet and yummy over ice with some branch.

12 year old, straight up. Too good.

Pappy Van Winkle 23-year old is the "best". I suspect those making other suggestions above have not tried it, as it costs c. $220 a bottle.

Makers Mark is good. My favorite is Bushmills, Irish Whiskey. (I guess that means it's not bourbon?). It's amazing how many movies there are where the characters are drinking Bushmills, almost always out of Baccarat Harmonie tumblers.....(????)

All whisky is good, but "bourbon" has a legal definition. Among other things it must be US made, mash made from 51% or more corn and aged in new, charred oak barrels. Bushmill's and Crown are not "bourbon." BTW, many of the nominations above are made at the Buffalo Trace distillery - they just use different recipes, and age them different lengths of time, in different parts of the warehouses.
