The core principles of geoinformation are the same across providers. Here is a map which is functionally geographic locations in specific locations, you place your own special bits in "layers" on the top. Leaflet.js is a great example of a library that works pretty much the same regardless of which provider you choose.

The competitive set is differentiated in some of their niche work (like specific-device-embedded maps, such as the ones in Tesla), but the first principles for the common developer are all the same.
