Regarding the fights themselves, I would recommend you take a look at One championship, especially their upcoming ONE ON TNT I and the other TNT upcoming fights. As the organizations are getting bigger and more financially backed, there is less and less reason to lock at it as a potential for fighters who can transfer to the UFC, but as a great outlet to see what former UFC competitors can do in other organizations (Rory MacDonald, Demetrious Johnson, Eddie Alvarez, Paige Van Zant to name a few)
Rory MacDonald is in Bellator and i do follow them but i am yet to watch any PFL or KSW fights nor have any idea about their fighters.
