They do.
I honestly don't think one is better than the other, I believe PV is actually necessary for thin rims, as SV holes just remove too much integrity and may make the wheel harder to keep true.
i think too much is made of the “integrity” issue. It’s really only 2 mm (8mm vs 6mm). Even a very narrow rim isn’t going to be compromised.
