Slightly apples-to-oranges comparison on the satellite count.
Unlike Globalstar, the Iridium network uses polar orbits which means they're covering a larger area and thus need more satellites to achieve comparable service in the limited latitudes that Globalstar covers.
(that being said, if you're going to be in mountainous terrain, higher latitudes, far from land, etc then Iridium will have better coverage)
