And to add, I hate stating the obvious but, there's an added x-factor when the model's teasing the one who films. You can see this across the board from Cosmid all the way to older stuff like starlight, swv and beyond.
It's just hard to achieve that when it's just a bunch girls filming cause they tend to just act all cutesy with each other, even if they are intentionally filming a sexy photoshoot. So that natural, authentic 1on1 interaction of the model seducing the filmer remains undefeated IMO
