Why do you rely on a study that uses advertised speed instead of actual speed like Akamai's? Akamai also has a category for 10 Mbps+ availability, and the U.S. ranks very well there too.
Because there aren't many international broadband studies that incorporate cost and I don't see any Mbps/cost breakdown in the Akamai study. The FCC report incorporates Ookla data (Speedtest.net) which uses actual broadband speed and costs submitted by users. It corroborates the conclusions of the FCC study.
With respect to availability: There is a world of difference between 1Gps@$1000/mth and 1Gps@$50/mth though both qualify as 1Gbps availability.
Finally >10Mbps is pretty broad bin today and fails to meaningfully differentiate "very" high speed services.
