Comment(by robe):
I think for the reason that Nicklas had stated that ST_Intersects in
theory should be faster, but I haven't done any official tests myself to
be sure. We tend to use ST_DWithin for most everything just because for
most cases we need a little bit of tolerance (or are working with less
than perfect geometries) which we don't get with ST_Intersects.
I would have said before 1.5 that ST_Intersects was most definitely
faster, but now that ST_DWithin speed has improved for larger geometries,
I'm not so sure.
