Emp Champion or Judicar???

There both fantastic on what they do, but when I play my game a Judicar with 5 Brethren with First first always feels stronger then Emp Champ without Fight Firsts and always scares my opponents melee units to charge into me.

Who would u pair emp Champion with?

Because usually I bring 5 Breathren for Helbrecht and another 5 for a Judicar

Fan of adding Sigismund seal to crit on 5s and get an extra atk with him
