Mailbox types: MBOX or MH

[Bryan Scaringe <Bryan.Scaringe@computer.org>]

I'd like to create a new mailbox folder.  My MUA, XFmail,
supports both MH and MBOX style mailboxes.  Which is
better?  Or rather, what are the pros and cons of each?
I would like to start using Mohogany, once its a little
more stable.  Will my choice of mailbox type make any
difference to that transition?

Thanks,
        Bryan
