Very nice. I really like that list.
3 supertall capitals:
1) Dubai
2) NYC
3) Shenzhen
Chicago being the top 10 too. NYC should eclipse Shenzhen overtime. Easily by 2020. IDK about Dubai though unless all the proposals are built.
I'm a stats lover, and I'd love to see a list for 100m to 200m and one from 200-299 for all of those cities for 2016 onwards. Lots of work though.
