And all of that was quickly undone with Bayley's anticlimatic win. Then the title became the Divas Championship when Anorexia Bliss won it, buried Bayley and Sasha, and is now in a Total Divas feud with workrate queen Nia Jax.Naomi already did that, but guess what?
Length of a title reign doesn't dictate prestige. The RAW Women's Championship was more prestigious while being traded between Sasha and Charlotte than Smackdown's title has been all year. Quality>Quantity.
By a small margin, I think the Smackdown Women's Championship is in a better place. There will be no ambiguity once Charlotte wins it.
