After working (internally) with Ion and related tooling, I'd say that I was opposite of fan. Protobuf strength is in good tooling/codegen around it (especially inside of Google), and with Ion you just have "superset of json".
Ion never had nice code wrappers around serialized structures, and most of the time, especially with rich structures it was frustrating experience.
