Mae IV question?

Granted it's an almost painfully obvious choice. I wanted to hear from the community to see if there was any suggestions or insight I'm not familiar with that could make her work better.
I currently have 3 different 4 ? Mae's.
Neutral
+RES/-HP
+ATK/-RES
I'm just curious since it is her one selling point that she has good resistance. There are a lot of different possibilities and want to hear some recommendations on which I should use and such.
