The absolute best whiskey I've ever sampled is...ta da...moonshine. Unfortunately the quality control of the product is usually all over the map. Ranging from engine starter fluid and drain cleaner to the smoothest tastiest whiskey in the land.
There used to be an excellent moonshine that was bottled and properly taxed and all that called, if memory serves, "Platte Valley Corn Liquor". It came in a jug, not a bottle. It was great stuff. I haven't seen it in years but then I haven't looked all that hard either.
As for other libations...
Perfidio tequila, if you can find it, is far and away superior to the Patron et. al. paint removers.
Never having developed a taste for scotch, I dislike it all.
Bombay or Beefeater's gin.
Vodka? Any premium brand will do. The stuff is supposed to be tasteless, so one tasteless is just as good as another.
