I'm new to both concepts so excuse me if it's opinion-based. Currently, I'm looking at Apollo Federation and schema stitching provided by the graphql-tools package, though I guess it applies to similar packages. Could something like a table be created describing certain requirements/conditions to prefer one over the other?

Apollo's GraphQL Federation and "schema stitching" both accomplish a similar goal: unify multiple GraphQL APIs under a single GraphQL API.
Based on my understanding, the main differences between them are:
- In Apollo's Federation, subgraph services own the logic for linking shared types together; in schema stitching, this logic is handled by the gateway.
- Apollo's Federation distributes the ownership of subgraphs to the individual service teams; stitching assumes centralized responsibility of the full schema.
- Apollo's Federation is tightly coupled to the Apollo ecosystem; GraphQL Tools' schema stitching is more open source.
