Marston's pantheon was more transformative though, his pantheon ruled over their namesake planets, had their cooler Latin names, used spaceships, and really were different characters all together (Mars had 'dukes' and slave armies, Venus and her butterfly girls). Perez's were a lot more generic, really indistinguishable from how the Greek pantheon is depicted in Disney's Hercules or even how they were shown in the Bronze Age.
But its still an aspect of his legacy. There is a direct line of thought between Perez's more mythological Wonder Woman and her becoming the daughter of Zeus.Now, this mythology gave rise to issues later on because other writers fell into the rabbit hole of myth retellings, but it was not Pérez's fault: he just added a marvelous shiny toolbox to be used with Wonder Woman. It's not his fault that later writers went "shiny!".
