To me, no other spirit beats whiskey. I don't really drink any other liquor besides it. I find, that if I have money to spend on booze, there is no other booze I'd rather spend my money on. I tend to lean towards the bourbons and ryes, American whiskeys, but I do love Jameson and scotch is definitely a tasty treat. If you have any whiskey, I suggest you pour yourself a glass and check out this short and sweet guide to American whiskey from GQ:
