Old saying - variety is the spice of life.
Few wine connoisseurs would restrict their palates to just cabernet or chardonnay styles. In SMS, the basic styles run from light, unpeated lowland to the more complex speysides with their myriad of "hidden" flavors, to the subtle peat smoke of the "in-betweeners" like Springbank, Highland Park, Bruichladdich, to the balanced peat-sherry of Lagavulin and older Islays, to the full sherry of Macallan and Abelour, to the real peat-smoke monsters of a young Ardbeg, Laphroig and the like. None of these fits all occasions and situations. While I may prefer an Islay as a final desert island dram, my cabinet contains some of all styles in nearly 50 bottles. My mood changes with the weather, the food, the company. I pick what sounds good for the day, usually moving from the lighter to the Islays as a final dram. But start with a Laphroig 10 yr. and keep it throughout the evening? Never. For me, it's the contrast in styles that brings the fascination and appreciation.
