I've never been to New York and Boston, so I cannot compare.

I've been multiple times to San Francisco and Seattle though, which I still consider to be first-tier US cities and their overall infrastructure* is certainly no match for Western EU's first-tier cities.

IMHO, one area where US infrastructure is markedly superior is the financial infrastructure (availability of capital, legal system) which is on the intangible side of things.
