There are currently only 2 panoramax instances. One from IGN (french "National Geographic Institute) and one from the french OSM charter.
This is obvious by looking at the coverage the world. France it where the majority of the coverage is. The coverage of most cities is actually pretty impressive for a young project.
While the UI and coverage is not necessarily on par with street view, it's still pretty usable in France.
Secondly Panoramax is first built for OSM contributors/mappers, not for end users. The blog reflects this in the tldr: "If you are interested in contributing"
