(ffjson author here) The main feature that ffjson has that most of the non-stdlib JSON libraries is stdlib compatibility. Eg, the same struct-tags and interfaces used in stdlib are used by ffjson. It's just trying move most of the reflection / allocations / etc to a `go generate` step vs runtime. If you abandon trying to stay consistent with the stdlib JSON, and make new APIs/interfaces for propagating the encoder or decoder state, as Gojay has, it will undoubtedly be faster than ffjson or stdlib.
