Just share some thoughts

REST is the typical HTTP method based transaction as compared to SOAP that is web service (XML based) API method driven. Different approach via web communication.

REST does not talk about any security. It totally relies on the underlying transport for security - let it be HTTPS via TLS/SSL mostly. In SOAP - it clearly defines a security standard which does not depend on the transport. WS-Security is designed for SOAP.

WS-Security offers more protection than HTTPS would, and SOAP offers a richer API than REST. WS-Security offers confidentiality and integrity protection from the creation of the message to it's consumption.

So REST via HTTPS ensure securr chnanel to the right server while SOAP via WS-Security ensures the content of the transaction is to the right server and able to be "open" up by the right application running on that server.

In term of performance, TLD/SSL is very much comparable but often much faster than WS-Security due to the latter's "additional" for identity and relying party  check.
