I'm really happy to see this sort of discussion happening within the GCC project. While LLVM/Clang are nicer and more usable than GCC in a lot of ways, in my experience GCC is still much more mature, generates better code, and has been implementing features new features from C++11 more quickly. I also like that GCC, glibc, and the GNU libstdc++ are all developed together so that as the compiler implements new optimizations and language features, the runtime environment also takes advantages of those features. I've been impressed with the last few GCC releases (I'm already using 4.7 for my own work). Competition is good, and it's great to see that GCC development is going strong.
