GCC doesn't always produce better output. A lot of networking code, like http daemons, as well as databases like PostgreSQL, tend to be sped up a bit by using llvm/clang. Also, the number of supported platforms for LLVM is growing pretty quickly; llvm/clang has support in the base tree for platforms like the MSP430, for example, that GCC doesn't.
