Well, Classic, easily wins. We know that she can fight blind with no problem whatsoever, plus stats, etc.. Speed next to him then hit him with a Zeus lightning blast is probably the easiest method.
Modern... hm, she might have a chance if he doesn't use his stone gaze (she's still stronger and tougher, and reasonably fast), but this Diana is more likely to have problems blind fighting and I think'd probably lose if she has fight like that.
Nothing, to my knowledge, but I also haven't read the past issue or two of her yet, though she's flying again... but she's still far below her standard, generally speaking. Hence, Standard makes for a clear win, but current would have to work hard to eke out wins, and isn't getting the majority, in any case.

Classic stomps, theres a noticable differnce in calibur between the two, and classic wondy is nigh on peer of superman. Lesser of course in every catagory physically, but she can hang.
Current Wondy is a differnt beast, she can win due to strength, but it wont be easy.
NewWondy jumped several thousands of feet from a plane without damage, just a small crater, and has thrown vehicles around. So her physical stats seem pretty high.
