Jockstraps vs Briefs

I see a lot of people talking about Jockstraps over Briefs or boxer briefs when talking about underwear without a pouch. It seems people tend to like them more. I imagine that is due to the Jockstrap being able to really hold a packer tighter than other styles?

I don't like the Jockstrap style and it won't work for me since I personally need the cloth to cover underneath. 99% of my underwear is boxer briefs or boxers with a clip harness or the cakebandit harness which I don't love bc of the Jockstrap design.

I'm curious as to what people prefer and why. Do people prefer Jockstraps because the packer is more secure like I imagine? Are briefs the same? What is your setup? I've seen a lot about harnesses but am curious as to how people keep their packer from moving in just underwear.
