For me FastMail's customers service has been better than Google Apps.

And had fewer issues in general with FastMail. Google Apps has some crazy limits, like on the number of IMAP connections or email aliases, you can't normally change the primary domain, you can't setup an abuse@ alias, etc, etc. and contacting Google Apps support doesn't do more than for them to tell what's already written in the docs.

And I mentioned in another mail, but FastMail's IMAP import and POP3 links work, whereas this functionality is broken for Gmail and Google's support won't help you ;-)
