The post mentions borrowing ideas from GraphQL and Falcor: if I used GraphQL or Falcor, is there some pain I'd hit that Om Next would avoid?

Yes, a few. Look for David's talk on Om Next he usually lists were he departed from GraphQL/Relay and Falcor. A big one is that both GraphQL and Falcor are string based, while Om Next uses data structures which are easier to programmatically manipulate and compose.
