Seems to me the reason for using studs is very simple. The threads in the
head will wear to a small extent every time a bolt is removed/replaced.
Multiply this by the number of times the bolt is shifted than add the
eroding effect of sticking through corrosion and you have the recipe for a
helicoil, sooner or later.

IMHO, the best combination is steel studs and stainless or brass nuts.
