Well, it is documented that Core Data's implementation of setFoo: is equivalent
to
- (void)setFoo:(id)newValue {
[self willChangeValueForKey:@"foo"] ;
[self setPrimitiveFoo:newValue] ;
[self didChangeValueForKey:@"foo"] ;
}
There are no branching statements in there.

It's better than either case you've proffered. I've always put my custom
behaviors in setFoo:. The only time I've ever messed with setPrimitiveFoo: is
when debugging.
