There are severals benefits:
1) Sun Studio is not only compiler. It has a lot of tools like
performance analyzer/profiler, memory checker ... There are group of
people who prefers these tools.
2) Compiler generates faster code on SPARC than GCC. If somebody uses
Linux on SPARC it helps him a lot. Code is faster on x86 as well, but it
is not so significant.
