Choose CoreFoundation if you want to do a lot of very low-level stuff 
by hand, and want the kind of control that comes from manipulating all 
the fiddly little bits close to the implementation.

Choose Cocoa if you want a lot of that stuff to be done for you and 
don't mind if some things are a little slower.

In some cases You effectively have to use Cocoa (or Carbon), or else 
build a Cocoa-equivalent on top of CoreFoundation.

I am not clueful about Rendezvous programming, but I've had pretty good 
luck with writing Cocoa and Carbon apps generally. Drop me a line if 
you want to compare notes.
