I've lived dense city to rural in the US, and it's suburbia that has the best internet. Can rip up the street for days no problem, but still a relatively dense population.

That's my sense, too. Companies seem to get permits really quickly where I live, and there are enough people around to make it worth their while.

AT&T, which already had cable here, ripped up the street a few months back and put in fiber. There are two other high speed providers as well.
