Honestly, I'm ashamed to kind of say it but I honestly have very little real knowledge of Wonder Woman beyond the vaguest notions and general aesthetics. Golden Age was full of starry eyed, kink-positive feminist utopianism, weird creatures and machines, Silver Age was a little more vanilla and heteronormative, Bronze Age had that period where she lost her powers and learned kung-fu from I Ching, post-Crisis started really leaning into the Greek Myth stuff, but also more did away with the likes of giant ridable kangaroos and the purple healing ray, and the pre and post-Flashpoint period leaned into that even more as the Amazons were portrayed as more and more warlike over time.
But I don't actually know much about Wonder Woman, I don't have the sort of engagement that comes from really spending a lot of time with the characters, world and material.
I don't know if post-Crisis benefitted Wonder Woman or not. I think there's probably good and bad elements, like with both Superman and Batman. If I had to pick pre or post Crisis for each of them though, I could do it. Maybe even for Flash or Green Lantern. Maybe. I don't think I could pick one for Wonder Woman though, just 'cause my knowledge is too incomplete. And that's kind of a shame.
