I like that it's easy to use with many different types of data sources (cloud or local).
It's also great for creating large scale models without having to purchase expensive hardware/software licenses. The only downside would be if you have an older version of mapwares product - they haven't updated their license key generator since 2013! Make sure your account has enough credits before purchasing additional licenses as this will help speed up the process once purchased. We are using MapWare primarily for mapping buildings but we're able to quickly create custom building footprints from aerial imagery which helps our clients visualize new construction projects more effectively than just relying solely on 2d drawings.
