Canadian suburban cities, Austin, Miami, and Las Vegas perform very well.

cool data, thanks for compiling it!

i kinda like how chicago's current top 10 tallest skyscrapers (or at least soon to be once One Chicago tops out early next year) break down into thirds, with one outlier.

since skylines are generally defined by their very tallest buildings, it gives the city a nice balance of new and old way up in the sky.

and IMO, all of them are good to great examples of the prevailing design styles of their time, with lone exception of 311 S wacker (too over-the-top for my tastes).
