Eve and Diana's powers aren't close and that was in the script and stated by Eve herself. Eve was shown to be unaffected by pretty much everything, including a room full of attacking wesen and the leader of BC, yet Diana shocked her to her core without even being in the same vicinity as her. And that was only a portion of her power as stated by Eve herself. As mentioned above, Diana took out Rachel and the mighty Bonaparte while being nowhere near them. Eve has to at least have eyes on her opponent. There's also the issue of Diana being able to read all of the symbols on the ancient cloth while Eve couldn't do it to that level even though she personally experienced the death grip.
