In the mid-priced realm for sipping I really like Eagle Rare. It's super-smooth and easy drinking but still has some interesting flavors. It's from the Buffalo Trace Distillery. It has displaced Woodford in that category for me.

My wallet hasn't allowed me to try enough of the "top-shelf" to lend a worthy opinion. As for bottom of the barrel, if Old Crow doesn't win I don't know what does.
