As much as I loath the way Byrne plays fast and loose with continuity, I have to say that the best thing about his Wonder Woman run was making Hippolyta the Golden Age Wonder Woman.
Yes, I know it makes no freaking sense even continuity wise. Yes, it was Hippolyta and not Diana. But I can't help if, after Crisis on Infinite Earths erased her from WWII history, my fanboy blood rushes when I see Wonder Woman back with the Justice Society beating the crap out of Axis soldiers where she belongs. And even the slightly retconned history that came out of that I didn't mind.
Polly had a great death scene, one of the few well-written scenes among the train wreckage that was Our Worlds At War. The wake held by Alan Scott, Ted Grant and Jay Garrick over a poker game still makes me "d'aww." And I still have mixed feelings about them bringing her back.
