Many of the peat phenols (or is it esthers?) tend to break down over time in the cask, so peaty/smokey scotches actually can lose flavor over time — though with a good cask they can pick up woody complexity. Younger islas tend to be more vigorous!
Edit: I don’t believe there is a requirement in the law to only use previously used barrels. They are just cheaper (boubon IS by law required to use only new casks, which results in a lot of availability), and aren’t quite as active, allowing for more gentle maturation.
I think this depends on your preferences. I like the Balvenie range, and that is easily available in 8, 10, 12, 16, 18, 20, 25, & 30 year old varieties.
For sure the 30 year old bottle is €300 compared to €30 for the 8 year old, and it is hard to rationally say that it is ten times better, but it is _different_ and it tastes great.
I'd never pick a bottle based purely on the age, but there are differences and I personally tend to gravitate to the 18+ ages when I'm picking my single-malts.
But beyond that, Scotch ages particularly slowly, because it, by law, can only be aged in reused barrels. A 10 year old bourbon is as old as the stones, because the barrels are, unsurprisingly, most reactive before being soaked with spirits for several years. Scotch, uniquely, mandates that the barrels cannot be first-use -- they have to be reused barrels from something else, which necessitates the very long aging times.
