Disclaimer: Im a beginner as well and all tastes are different.

That really depends on you. Which you will prefer is imposssible to know. However I can compare them to Glenlivet.

Macallan 12 for more Sherry Flavor (Sweeter).
I believe a traditional 10 yo OB does exist but it may be limited to GB as I have never seen it in the USA.
The "Fine Oak Series" in my opinion just isnt the traditional Macallan. I really dont care for the FO and I suspect Im not alone.

Highland Park 12 for a little more of everything.
It is known as the "Great All-Rounder" for a reason. It is very well balanced.
I find the flavors tend to change order of predominance with the weather and my mood.
Highly recommended. (Disclaimer: May be influnced by the HP12 currently in hand).

Taliskar 10 - Peppery and Smoky.
(Disclaimer: No personal experience.)

Bowmore 15 - Bring on the Peat.
Kind of a poor mans Lagavulin (local pricing). It is known to have an unusual wide range of "Cask Variation" so you will get some flavor drift from batch to batch.
