Favorite character, character you think is underrated/overrated, and character you hate/dislike?

Hello, I had the typical question about what your favorite characters are but I wanted to extend it further, what is your favorite character and why? Which characters do you feel receive more love than they should and characters who deserve more love, and finally, which character do you not like or hate to see?

I start with my favorites which would be Polaris, Magik, Jubilee and Gwenpool
