Aberlour 12 is one of my favorites at its price point ($34). The Balvenie 12yr Doublewood is also a fan favorite at its price point ($48).
I've tried the Macallan 12yr, Glenfarclas 10yr, Glen Gariach 8yr, and others, but for me, the Aberlour 12yr represents the best bang for your buck.
The Aberlour A'Bunadh is also one of the best whiskies in its class. I enjoy the Macallan Cask Strength as an alternative to the A'Bunadh, as I find them very similar and the Mac is cheaper in my area. I understand that the Glenfarclas 105 is in the same vein as the others, but I haven't tried it yet. I have an unopened sample in my cabinet, waiting for me to taste it.
I also have a special bottling from the Arran, a whisky matured for 11yrs in a single sherry cask. It has an ABV of 56%, so I expect it to be similar to Mac CS and A'Bunadh, but with a fuller and richer profile (smoke & pepper spice). However, it is also unopened, so I don't know for sure!
