There are a couple studios with similar styles. Phat Pharrah, mostly for the Mila Rose fights. Mila vs Bella Ink is up there for me as one of the roughest catfights ever(with rules obviously). Catz Review out of the UK is good for hard slapping and hair pulling. Tillytown has the best trained all around fighters. If you want to see experienced fighters with great wedgies/breast attacks, I'd recommend watching Lyric's fights. Her fights with Davina has some of the most vicious tit maulings ever.
But like DJP60 mentioned, SF is in a league of their own. The total package when it comes to quality, presentation and fighting. It's like a modern day ECNWC, from the lingerie/robe intros to the interviews before and after the fights.
