I like my gods as modern as possible and weird. Not weird to the point of looking stupid or goofy, but creepy and macabre. I think the weirdness fits Wonder Woman's world and it's a great update and replacement of the Golden and Silver Age's wackiness and hijinks. Though not a god, a case in point is the Keeper of the Grounds in the latest issue. Giant man dressed in ominous Edwardian clothing, with the head of a bird, a huge hat and a lantern on a weathered stick...it's a cool design.

To the contrary, while a similar concept the depiction of Athena in Azzarello's run just looked stupid.

There's a fine line artists have to walk. To that end my favorite versions of the gods are...
Ares with blond hair as the God of Conflict, black hair as prisoner of Themyscira and horrifying in armor as drawn by Liam Sharp
Apollo and Artemis as twins Sun and Moon
Phobos and Deimos as foppish 19th century brats
Athena with her owl on her shoulder and laptop in hand
Perez Poseidon with the bubble beard and massive trident
Hephaestus with molten rock arms and Hellboy influence
Aphrodite invisible so you have to use your imagination
Hermes golden flower delivery form from Earth 2
Demeter dreaded African earth mother
Hades with the candles but Rucka's undertaker was cool too
Strife is always preferable to the female Ares form of Eris
