Well, not to be the uber nerdy comic book nerd here, but Poison Ivy's skin isn't actually deadly to the touch. Not constantly, anyways. On the last page of Chapter 5 of The Long Halloween, she either touches, or it's implied that she will soon touch, Bruce Wayne, skin to skin (hard to tell with the artwork), and in Hush, Poison Ivy backhands Catwoman across the face. Neither of them suffer any abnormal effects from this. (By the way, I don't know all that offhand, I had to look through my collection to make sure.) Poison Ivy CAN exude toxic chemicals, and her bodily fluids (usually her saliva, but it's safe to assume that other bodily fluids would be the same way) are toxic.
So, in short, I'd pick Poison Ivy, but safe sex is a must.
I'm not sure whether or not I should be proud of this post...
