Well, the first big advantage is that it actually works, while the gcc
that comes with NetBSD does not. :-)) *ducking and running*

Seriously though, it doesn't really make a difference whether you use
objc or gcc. gcc is probably(!) a bit more reliable with complicated
code and it is supported by more users than objc is. objc does have a
few nice features, though.

For one, it can compile an Objective-C file into a plain ANSI-C
source. (In fact it does that all the time, since it is a
pre-compiler.) This might be useful for people who don't want to
distribute Objc-C sources, because many people can't compile them.

Futhermore objc supports code blocks and exceptions, what gcc doesn't
do at all.

Last but not least, objc has in-built support for object garbage
collection --- what can be patched into gcc, but isn't included in the
vast majority of installations, I'd say.

I personally use gcc for development and occasionally I check whether
my classes do compile with objc. If they do, that's a good test
whether the code is portable or not.
