The short answer (from someone that was in the project team of S/MIME implementations for mutt and kmail and support for PGP/MIME for Kontact Mail and the Outlook plugin for Gpg4win (my roles did include technical coordination, analysis and testing.): I am on the PGP/MIME side of things, I recommend it as default for sending out emails. See also http://wiki.gnupg.org/SignatureHandling . a) for encrypted emails, there is no drawback. Every email client just have to be able to deal with message/rfc822 mime-parts anyway. b) for signatures, https://www.gnupg.org/faq/gnupg-faq.html#use_pgpmime lists the drawback that some transport agents will modify attachments. In the past I've published a number of patches and problem reports to Mailman, so I know this issue quite a bit. It is due to a missdesign of the python email package and it should be fixed. (And it is fixable by a reasonable effort). Another drawback is that some proprietary email clients (like outlook) do not enable someone to influence the mime-structre. This is the bigger issue of course. On the other hand, the advantages are clear and PGP/MIME seems the best design given current standards and practure of SMTP and MIME. And given a reasonable mime library, the implementation for creation is much easier as for parsing and should not pose a major problem.
