Neither could I until I visited the distillery in Oban, after the tasting I realised how good a single malt could be. WG I have now progressed to Talisker which is my favourite.
Talisker is indeed a fine drop. Since you like the peaty ones, maybe you should try one of the Islay malts, e.g. Bowmore, Laphroiag, Lagavulin, Caol Ila.
And to any heathens reading this, yes of course you are invited up for a tasting. Easier still, pop into your local pub and try a
single malt at my expense. Just tell the friendly bar-keep to charge it to WG's account.
Suggestions (since most folks find the peaty ones an acquired taste) : Macallan, Balvenie, Glenmorangie, Glendronach, Highland Park, Glenlivet. Very mild whiskies would be Glenturret or Glenfiddich
Serving suggestion : Neat or with just a little chilled water. I usually have a glass of iced water to sip separately.
