Sulphur can be good, intriguing, as long as it is at one end of the spectrum. A low level can add a topping to the richness of a whisky. This line runs from spend matches to over boiled cabbage and everything from bad eggs, rubber bands and warming tyres; the scent of a spent match being the more generally acceptable end of the category.
