Better a better skyscraper "threshold": 100m or 150m?

Like Steely, I subscribe to the 500ft and 1000ft (150m and 300m for the metric inclined) out of a historical sense. When I started looking at them in the late 1980s, only a select few cities had buildings over 500ft (NYC had like 105 in 1988 IIRC) and it was a nice cutoff. Most of them were office buildings because the residential skyscraper explosion hadn’t happened yet.

I though, also have a special spot for the 700ft (213m if need be) threshold, which up until the late 90s I had memorized. It was a very special city that had one (or more) of those. That changed significantly in the mid 90s. My first trip outside North America was in 1998 to Taipei, HK, and got to see Shenzhen from a distance. At the time, that captured a substantial handful of the non-NA 700ft ers for me. I once had a goal of seeing all of them.

Edit: in 1999 there were approx. 196 such towers in the world. I've seen 144 of them! Now there are over 1,600 and I certainly will never see all of them.
