The major differences are: 1. tptools/graphql provides all Wikibase DataModel features without simplifications (e.g. you get reference hashes, time calendars...) 2. tptools/graphql does not use property labels but Pids to identify properties. It has the advantage of being more stable (no change introduced if a property label is changed in Wikidata) and making the GraphQL schema independent of which properties actually exist and what are their datatypes. 3. tptools/graphql is written in PHP to see if it would be possible to implement a GraphQL frontend as part of the current MediaWiki codebase. 4. tptools/graphql provides a way to call SPARQL from GraphQL.
