Jace is a try harder, well, mtg tries to hard to make jace cool. The looks, the oneliners, the arrogant, mysterious and emo look. And that's why I don't like him.
It's like old Dante and New Dante, with new Dante they wanted him to be fucking cool and they failed miserably, old Dante is charismatic as fuck.
My fav planeswalker is either Gideon or Garruk.
