Wonder Woman. Ya'wara just doesn't do it for me. Must be the hair.
On the matter of Diana's artists, I think both Chiang and Daniel bring their own styles, and both are talented artists. Chiang's Wonder Woman looks more grounded...I don't want to say butch, but her proportions are more realistic I guess. When he does slim down the midsection, he can draw quite an attractive but still practical Diana though:
Daniel's Wonder Woman is more standard superheroine, but you know, that has its merits as well. His WW certainly has a more shapely figure, but on a whole, I don't think he falls into the extended-bosom-and-bum or super-skinny-waist Liefeld-esque problems in general.
