Usually the head pops off the nipple.  As I said, threads strip during
tightening but heads pop off from fatigue and tensile stress.  On
loose surfaces (not clean dry pavement), the place where sticks most
often get in a front wheel, the rim usually comes off OK as you do an
endo over the bars.  This is not a reason to choose one type of nipple
over the other.
