Scotch! I've had everything from the bottom of the barrel (no pun intended) to some of the top single malts, and here are my favs:
Extra cheap: Clan MacGregor. Strong alcoholic taste, but has character. Great when used as a mixer or on the rocks. Not bad at all for the $7 or so
Cheap: Lismore. Very smooth, yet complex single malt. Best under $55 IMO (WAY better than Glenlivet/Johnny Walker), and my regular.
Mid-price: Macallan cask strength. Not much has to be said about this one
High end: Macallan 25yr. Extremely woody overtones, good bite, use this one as a mixer and you will be damned to the pits of eternal flame!
Extreme high end: Macallan 30yr. Takes the best qualities of the 25yr and removes a bit of the alcohol bite. A bit too woody for my taste, but a bit better than the Laphroaig 30 IMO.
I do enjoy a little Bourbon every now and then though, and I usually reach for Weller's special reserve.
