It's the supporting libraries. GraphQL itself is fantastic and solves so many of the issues that crop up when using REST, especially around excessive requests, extraneous data and poor transaction support. My team's core knowledge is in Python and Django so that's where we're most productive, even hamstrung by the tools, but with a bit more flexibility in timelines I'd probably go the typescript/node/apollo route.
