My initial thoughts on the map folio are from using the PDF version.
The stylized map of the Ruins of Azlant region is the highlight of the package. Useful for annotation as the players progress.
The GM's map of the region seems underbaked. The names of the major islands, and a couple of arrows pointing to Talisantri and elsewhere. Not sure what use this would be. It would have been far more useful if the locations from each book of the AP were labelled, 1A–Z, 2A–Z, etc, so that the GM could see where everything takes place.
Lastly the map of Talislantri. Almost completely unlabelled, I'm not sure what this is intended to be used for? Not enough information for the GM or the players, unless you intend to write locations onto the map.
The lack of layers in the PDF is a problem as well, as it would have been possible to create GM, player, and display versions of maps, simply by toggling sets of labels.
