Jyn BM or Summoner dungeon farming?

[Herbs]

Which of these is better for mushin tower, farming outfits ecT? But can still hold their own in PvP, I have played both until about lvl 15-18 but It is the little things that make me want to restart like the way summoners look in outfits ect... I have also gotten Destroyer and assasin to 18 but cant seem to get into them...
