Time to de-lurk a bit.

Sun Studio is significantly better on SPARC (faster compilation and 
faster compiled code). I haven't done comparisons on i86pc/amd64.

I think that Sun Studio is a requirement within Sun for building things 
in Solaris and OpenSolaris OS. This is probably the fundamental reason. 
Of course, non-Sun built OpenSolaris distributions are free to use GCC.

Personally, I find that "monoglot" code is usually the worse for not 
getting any second (or more) opinions.

That is a reflection on the poor support of the platform/compiler 
combination (mostly by WebKit, and partly by Nokia).

Sun Studio can build everything. Some patches are required. Most of 
these are due to Sun Studio being rather strict (IMO a good thing, but 
I'm  stickler for real standards). There are a couple of template 
issues, but I'm not good enough at templates to say whether they are 
genuine ambiguities or not.
