Best female champion ever?

[TerrorTimmy]

It's not a who, but a what. Cyborg is 26-2 (21 finishes). Nunes is 23-5 (17 finishes). Cyborg has 15 title fight wins. Nunes has 11. Cyborg has essentially been a champion non-stop for the past 14 years. Nunes's reign has only been half that.

As for Nunes beating Cyborg, that holds about as much weight as Serra beating GSP, Conor beating Aldo, or JDS beating Cain. It's a good win, but also a win that by itself doesn't prove much, given that the two have only shared the octagon for 51 seconds. Anyone can get a flash KO. What happens if that one shot doesn't land?

Quality of competition matters. Amanda fought better opponents. By far.

And that wasn't a "flash KO"

Since you're re-writing history here, I'm done. Can't have a real debate with someone who can't acknowledge facts.

Imma just leave the numbers out there and you can make your ranking.

-Valentina Shevchenko (FLYW): 7 title defenses in a row, 4 finishes
-Ronda Rousey (BW): 6 title defenses in a row, 6 finishes
-Amanda Nunes (BW): 5 title defenses in a row, 6 title defenses overall, 3 finishes
-Joanna Jędrzejczyk (SW): 5 title defenses in a row, 1 finish
-Rose Namajunas (SW): 2 title defenses overall
-Zhang Weili (SW): 1 title defense
​

Julianna Peña, Jessica Andrade, Carla Esparza, Holly Holm, Nicco Montano, Miesha Tate and Alexa Grasso are girls that have got the title but have no title defenses (yet).

I'm not even going to count the FW division since that one has always been a joke (can't even make a top 5 out of it).

So the one with the most title defenses is Valentina (7), the one with the biggest finishing rate is Ronda (100%) and the one who has fought the toughest competition idk because that one is subjective but I usually hear ppl putting Amanda in that regard

How could it be anyone else but Amanda? Then Valentina. Between Joanna and Ronda I'd need to think more about

Amanda has undoubtedly the best resume. It's hard not to put her first, even though Val should have gotten the nod in their second fight.

I think Val is the most skilled of all the female champions, but her resume isn't as strong due to fighting in what has historically been a very weak division.

Rousey was the most dominant champion, but her resume sucks.

Joanna has a very strong resume, and her long reign puts her up there.

Rose is likely the most skilled of all the female champions (after Val), but she simply isn't consistent enough to put her above many of the other contenders here. Too many lacklustre performances, and not enough top wins.

Zhang is obviously very good, and beating Joanna twice was amazing for her resume. But she hasn't been at the top long enough to consider her the best.

From those mentioned, my list is probably something along the lines of:
1. Amanda
2. Val
3. Joanna
4. Rousey
5. Rose
6. Zhang

Worth noting that I think 1-4 are leagues ahead of 5-6 in terms of being a "great champion". Rose and Weili simply don't have enough title defences to be held in the same regard as the others mentioned.
