LLVM is much more compartimentalized, so we can make changes to the backend without touching/breaking other parts. The GCC loader was miles ahead of the LLVM loader up until the past few releases, and we were originally using a modified version of the GCC loader before switching. LLVM also has a bunch of awesome projects like Poly for polyhedral compilation that we are able to use that don't exist at all for GCC, or are very difficult to integrate. LLVMs lego block like architecture (it was originally designed as a tool to help build toolchains) plus things like Tablegen enabled our single "real" software engineer/CTO to do initial bring up of a backend in under a month.
