Macallan 18- Liked it, but wasn't especially remarkable
Aberlour 18- Like it a lot. Right flavor for me
Besides that I've mostly stuck to the 12 years, which are never incredibly special.
Surprisingly never heard of it, even after spending a couple years in Japan. I'll look into it.
Glenfiddich is a damn good Scotch. It's a single malt, and the last time I got a bottle, it was under $100.00. Great Scotch is like great wine: if you don't have the palette to appreciate it, it's not worth the money.
Never serve it chilled, room temp only. If you can't take it straight, mix it with an equal amount of water. If you have to have it cold, one ice cube only! Too cold and it masks all the flavors it has to give.
Before you drink, take a normal breath. Take a sip, coat the inside of your mouth with it for a few seconds. Swallow, then slowly exhale. As you do, pay attention to what your taste buds are telling you, and you will perceive the the change in the flavor. The more you practice, the more of it you will "get." It's a lot like drinking wine, in that respect.
Enjoy!
and if you find you don't like it, and some people just don't, hey ... there's always Vodka!
