Trevor Perrin also went on and created the Noise protocol framework (of which some protocols are quite similar to Signal).

[RRRA → dom0]

Interesting, didn't know he was also involved with that one.

Has anyone seen a table comparing Noise, Axoltl & OTRv4?

[tptacek → RRRA]

Those aren't comparable.

Noise is a metaprotocol, a framework of patterns for building secure transports.

Axolotl is a cryptographic ratchet construction, for continuously modifying encryption keys as messages are transmitted.

OTRv4 is a complete message cryptosystem, like Signal Protocol.
