Jack Daniels is pure shit, fact. Well commercialized but that's about it, the quality for a whisky is utterly crap, it,s ok for Rum and coke or other mixes but to drink pure, other than to have the skin of your cheeks removed Best whiskeys on earth quality vise are (imo) by far the scotch whiskys, you have some irish one which are top of the mark as well and the japanese for the couple past years have produced something top notch, especially the Santori. Personally, my favorite ones are the Talisker, Cao Ila and Laphroaig but many specialists will argue in favor of the MacAllan as perhaps the best scotch whisky (the process of olding is made in porto cask now which gives it a very special flavor).

As for Vodka, the best ones I own are the Stolichnaya ELIT (to not confound with its sister the mere Stolichnaya) and the Ultimat, damn difficult to find but once again, when you drink that, you know that it's not your average Troika or Smirnoff. These are even above the top qualities like the Grey goose or the Belvedere. Still, I couldn't refuse a grey goose or a Belvedere anytime of the day, damn good produces.
