#1 Worst: Miss WrestleMania Battle Royal (Wrestlemania XXV)

Of all the Divas Era matches, this was by far one of the worst. The battle royal features both past and present female talents in the WWE which included the likes of Sunny and Molly Holly, among others. But instead of having separate entrances, the women came out to a Kid Rock medley without being introduced. Michael Cole even referred to Gail Kim as "one of the Bella Twins" when Kim was eliminated.
And to make matters even worse, the Miss WrestleMania Battle Royal was won by male superstar Santino Marella, disguised as a woman.

Fortunately, these kind of matches will never happen again in the WWE as the women in the WWE are being taken very seriously now.
#1 Best: Charlotte Flair vs. Sasha Banks vs. Becky Lynch (WrestleMania 32)

Throughout the history of the WWE, this was the match that changed women's wrestling in the WWE forever.
By early 2016, it became very evident that the term "WWE Diva" carried a negative connotation with both past and current WWE Superstars and fans alike as the term portrayed WWE's female talents in a negative light courtesy by labelling them eye candy.
To remedy the situation, it was announced during the WrestleMania 32 kickoff show that the Divas Championship (AKA the butterfly belt) would be retired and replaced by a new WWE Women's Championship, not to mention that the women would be known as "Superstars" just like the men from that day forward.
As for the match itself, it featured three of the "Four Horsewomen" (Banks, Flair and Lynch) which lasted for sixteen minutes as Flair forced Lynch into submitting, becoming the champion in the process.
This match also set the model for future WWE women's matches to come.
