I haven't used Keil or IAR, but comparing GCC to SDCC, it seems to me
that SDCC is a more primitive compiler.  There's a bunch of features
absent and the error diagnostics were often unhelpful.  I've used SDCC
twice.  Once was starting a small project from scratch, which wasn't too
bad.  I just dealt with issues as they arose.  The other was attempting
to port a midsized project (around 5K SLOC) from GCC to SDCC.  It became
clear pretty quickly that getting an SDCC version working at all would
be considerable effort and the resulting binary probably wouldn't fit on
the target cpus I was thinking of.

I'm not at all trying to bag on SDCC since it is obviously useful, but I
can understand why people sometimes look for more featureful compilers.

Finally, although both programs mentioned were written in C, GCC can
also compile C++, which has some attractions.  I don't know if IAR or
Keil compile C++.  I also remember thinking that it would be interesting
to write embedded applications in Ada, and GCC compiles that too.  Right
now I think there are no non-GCC compilers for Ada-2012 or later.
