Suitefights #1 hands down. Real and down right authentic. All others scripted IMHO.
I agree that SF is #1, but Slap City and MexicanCatfights are definitely not scripted.
None if the current catfight producers come close to ECNWC. Maybe it was a different era or the way Bob paid the girls, but those fights were as authentic as they come. Watch Sarah vs Kelli or Chikara vs Lauren and you'll see what those catfights with animosity look like. None of the laughs and giggles that you get now a days from many of the fetish models.
