The images show exactly why I personally need to wear panties. Since they go down the leg and hold snug, too much movement can be quite uncomfortable with where that stitching. It'll move and rub, and even though you may think that sounds erotic, it's more like a saw after a while.
It all depend though, on the brand and quality of the hosiery, what you're doing, and how long you plan on wearing them. But if I'm going without panties, I'll either not wear any, or go with stockings.
