Mailbox; I wish I converted when I had the chance. The only benefits
I can see with mbox is that it's slightly less complicated, and if
you're doing pattern searching or some global mailbox operation, less
I/O intensive, but that's a niche case and usually ameliorated by indices.
However, backing up mbox is a pain since changes results in the entire
file being backed up for snapshotting filesystems, and atomicity of
I/O operations is much harder. It just doesn't scale well for large
mailboxes.
As Aki recommends, use something other than mbox unless you got some
legacy issue.

Lots of third party scripts out there that will convert for you. I think
you can do dovecot->dovecot dsync to convert.
