What is the best icon for settings? [on hold]

While we were discussing UX at work, we stumbled across this question. Which icon is the best icon for settings, wrench or gear? We simply just need to figure out which icon is the best for settings and if there’s a difference in that opinion depending on where people live. Thanks for sharing your opinion.
