Actually... it's about the same.  Using vectors is the whole point of SSE.  If you look in the xmmintrin.h, you'll 
even see how it's pretty much the same:

   /* The Intel API is flexible enough that we must allow aliasing with other
      vector types, and their scalar components.  */
   typedef float __m128 __attribute__ ((__vector_size__ (16), __may_alias__));

   /* Internal data types for implementing the intrinsics.  */
   typedef float __v4sf __attribute__ ((__vector_size__ (16)));
