If as per the OP we are talking about "the Americas", many Latin American cities can make a pretty respectable showing.

Especially in countries that had or have a decent standard of living and gave themselves fairly impressive capital cities.
I think that most anywhere in the new world, architectural styles initially mimicked the architectural styles of the European colonizers, though some places more quickly and more dramatically moved away from the Euro style, for a variety of reasons.
Architecture and urban form in most of Canada and the U.S. have become quite far removed from the European model, obviously. Mexico I also find to have its own style - even the older, charming parts of Mexico clearly feel more Mexican than they do Spanish or European.
OTOH places like Buenos Aires (shown above) favoured "Europeanity" for much longer and over a much larger imprint within the city.
