I agree with you on the fun Wondy used to have! :)
Also, Golden Age Steve always impressed me by his admiration of his Angel's power and skills. :)
Ditto on Silver Age Steve. They turned the comic into a romance comic and made him a jerk and Diana wimpy.
I do think that early '80s Steve was written pretty well, though. I also think that DC missed a golden opportunity to bring their relationship as up-to-date as Clark/Lois after the reboot in '86, but instead pretended the relationship had never existed at all.
