Sure:
Coenen: best opponent, took Cyborg to the 3rd and 4th rounds in their two fights. Formerly fought at 135, subbed by Tate, and has a loss to Roxanne Modafferi, who now fights at 125.
Carano: Arguably her second best win, but had only seven fights at the time of her Cyborg fight, and like Cyborg, often fought women smaller than her (such as Rosi Sexton, who fought at 125 and most of her wins are over 135lbs. women (Kedzie, Evinger, etc).
I have no idea who you would consider her third best win. Shayna Baszler is in the top five at the time, and she has fought at 125, and when fighting at 135 can easily drop bodyfat on fight night. She was routinely criticized for her skill and ability when fighting in the UFC at 135.
25% of Cyborgs competition fought at 135, stepping up for a fight/payday. An additional 25% fought at least two weight classes down, and stepped up for a fight and/or payday.
So I would describe her competition, with one exception, to be very, very poor. Sure, Carano was hot, but fight-wise, she was not all that.
