They would be much less homesick, since it is an event-loop based editor like any other MacOSX application, and MacOSX editors using the default setting of NSText objects on NeXTSTEP OpenSTEP and Cococa, implement already the basic emacs control keys, with which the user may already be familiar.
But you will see a big increment on productivity only if you start learning emacs lisp and start writing (program) your own commands to automatize your editing or code generation in a personnal way. Or if you're lucky, there may already be an emacs package implementing your exact needs and it will be helpful, compared to an editor with a fixed feature set.
