I know a lot of people aren't huge fans of many of the standard expressions of Diageo's Classic Malts series, but I personally like them as affordable go-to drinks.
Cragganmore 12 and Dalmore 15 are great.
Caol Ila 12 is a very sweet peaty scotch.
Oban 14 is okay, I had it last night and wasnt very impressed. It was a spicy highland without smoke.
I like Glenfarclas but I'm liking sherried whiskies less and less these days. They smell so gross to me now. I had a sample of Glenfarclas 40, and it was great. Sherried whisky without the sulphur is great!
I would do the glenrothes 1994/2010 if you can find it. It's basically the same cost as the 1998 where I live and it's great stuff.
Have you had glenmorangie yet?
I know a lot of people love their malts but I just can't stand them, and not just because every single one I've had has a lot of sulphur. I dislike their whisky because the spirit has a strong rubbing alcohol taste to me. It's really harsh and it makes me think I'm drinking cheap, young whisky. Also, every bottle I've bought the cork disintegrated when opened and ruined the whisky. Plus, like I said, it has the most sulphur I've ever tasted in a whisky brand. And it's not a lack of trying. I've had their Quinta Ruban, Lasanta, 18 ER and the Finealta. The Finealta was the best one I've had, it had the smallest hint of pest I've ever had, which is awesome for me because I'm not a huge fan of peat.
One of my favorites is highland park. It has been rated as one of the best all around whiskies and the 12 year is very affordable for what you're getting. The older expressions have more sherry and sweetness from a longer time in the sherry butt. The 18 is usually rated the best, some places it's $80-90.
