Why better?

Via is a MUST https://tools.ietf.org/html/rfc7230#section-5.7.1

Forwarded is OPTIONAL https://tools.ietf.org/html/rfc7239#section-4

Protecting against loops only works with MUST headers.

Additionally, Forwarded is only for requests, while Via is for both requests and responses.

Makes sense. Thanks!
