It depends on the specific mesh which is more memory efficient. I
expect that in the typical case only a small number of vertices needs
to be split, and the extra memory ends up being smaller than the extra
memory required for storing all normals per corner. Game engines do
such splitting too, but for all attributes including UVs, that would
likely reduce memory usage further.
