For anyone reading this now, since January 2013, Clang 3.2 is probably the most comprehensive C ++ 11 compiler, although the last Dev GCC branch (4.8.x) is about to bring GCC back to its original position.

Just look at this support table! Epic stuff. This only applies to currently available stable versions, and the GCC table contains about 4.8 entries.
As I said, when GCC 4.8 gets into a stable release, it will again be tight between the two:
