Batman's main set of rogues are among the best in comics, but like it has been said it's because they are immortalized in other media. The main set only consists of 15-20 or so characters (basically the ones who made it onto BTAS, who are also used in big roles in movies), once we get beyond that we get into the b-list and below and they really aren't any more remarkable than anyone else's villains. He has a ton of them who fell by the wayside and were never heard from again: anyone remember Steeljacket, Gearhead, Nicholas Scratch, Echo and Film Freak? Probably not.
Of Superman's villains, Lex, Brainiac, Mxy and Bizarro are all great, and even though they are mooks Parasite, Metallo, Toyman and the Prankster have their moments/potential. You could roughly get a similar number of iconic and popular foes from Superman. Also Wonder Woman, most of her villains haven't been seen since the Golden Age, and while they are dismissed as lame they really aren't any sillier than Batman's.
