* MapCodes are shorter by 200-300% for a given accuracy level, assuming each MapCode is prefixed by a two-letter country code for clarity.
Cons of MapCodes vs. Geohashes:
* MapCodes only offer one accuracy level, of apprx. 100 m^2 regions, whereas a Geohash can be arbitrarily accurate.
* MapCodes do not guarantee persistence. They can be redefined at any time, for any reason, at the sole discretion of the project designer, leaving you with a nonreferential or falsely referential code.
* MapCodes do not encode location data within the code, so access to the server is required at all times. If you lack internet access, or if the service is DDoSed, hacked, goes out of business, etc. your codes become useless.

So what's the upside of this vs Geohash?

patents and ambiguity where you have to also mention the country and sometimes, but just sometimes, the state.
