The micronormals tend to produce a grainy result even with lots of
samples. OTOH antialiasing usually makes the result better (rather
obviously, as more samples will be taken per pixel).
Macronormals tend to produce good-looking result with less samples,
at least if the amount of blurring is not large. If you need just a little
bit of blurring, macronormals will often be a better choice with respect
to rendering times.
OTOH if the amount of blurring is large, or sometimes also in other
situations, macronormals can produce visible and ugly banding. This is
not helped by antialiasing.
So it's always a compromise either way.
