| The high-performance serialization and deserialization algorithms in the msgpackr package are also available in the [cbor-x](https://github.com/kriszyp/cbor-x) for the CBOR format. A quick summary of the pros and cons of using MessagePack vs CBOR are: | ||
| * MessagePack has wider adoption, and, at least with this implementation is slightly more efficient. | ||
| * CBOR has an official IETF standardization track, and the record extensions is conceptually/philosophically a better fit for CBOR tags. | ||
