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

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

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

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.
