There is _no_ objective measure of quality when it comes to whisky so all we have to go on is personal preference. When Murray benighted the 2013 Yamazaki, that was _his_ personal preference against _all_ whiskies reviewed, peaty, smokey, or otherwise.
And you can _absolutely_ compare a peaty/smokey whisky to one that isn't. Why can't you? Peaty/smokey isn't the sharp divisor of preference that is insinuated in yours and other comments. Peat is delivered in very unique ways across distilleries and in my tastings I often have folks strongly dislike Ardbeg Corryvreckan but adore Lagavulin 16 (as an example).
