Super talls are like whip cream atop of a really good latte. The skyline needs to be aesthetically good for them to really work (aesthetically) and in the right location. Think of them as seasoning to a really good dish. But if the dish is bad to begin with, it will be out of place.

The super tall addition to SF for example, really adds a new dynamic to the skyline. It complements it. Doesn't look out of place nor does it ruin the skyline. LA's new supertall again, has that perfect touch to an already balanced skylined. NY has the buffer of the skyline mass, and what's going on really doesn't stick out in a negative way.

What is bad now, is a lone super tall that looks like it was just plopped out there. IMO, a gradual progression of height and mass makes a super tall look its best aesthetically. In other words, its not the design that really makes a tower have an impact, but how it interacts with its surroundings.
