I've used Gandi for years, but only migrated to FastMail fully about two years ago I think. The migration was painless, much more so than I expected, thanks to the integrated support for migration. It's a great setup, can't think of a single instance where I've had an issue with it. It just works. The only thing really bothering me is that you can't seem to set a default email app in iOS so mailto: links won't open the FastMail client. This is a super annoying client issue, but the service works incredibly well, no complaints here. N.B. I have no affiliation with FastMail or Gandi whatsoever, just a very happy customer.
