Zeta Maul or Vader first?

About to be able to Zeta my first toon. Not sure if I should go with a zaul team or a zader team that's sith/empire. If zaul is more viable than zader, who should I replace shore with? Any comments/critiques are welcomed.

Current squad is:

EP (L)
Vader
Maul
Shore
Anakin
