In my opinion (with limited experience mind you) a snap is much more secure. However, done properly (hole in strap not oversized, stud head to neck ratio substantial enough to capture the strap and properly tensioned) it should be pretty dang secure, enough that you wouldn't have any worries about the blade becoming easily dislodged. On the flip side of why a stud is better, the chances of rubbing against something and having the strap on a stud release are less I feel than that same scenario with a snap.
