Even worse, delivering email over ipv6 to the mail giants is a far worse experience than via ipv4. More emails arrive when you disable ipv6 on your mail servers.

I would say the same experience as long as the server and supported services are configured correctly.

If you google correctly you'll find many people compiling about google not accepting mail via IPv6. Therefore not many people do SMTP via IPv6. Or if they do they have an extra (v4 only) transport in their outgoing SMTP server. ==> Runing Dualstack is more work.
