Semira applies Poison, Paralysis, Curse, and Weak (80% chance for all), 35% BC and HC drop rate increase, removes and nullifies status ailments.

Ciara adds 140% Atk, Def Ignore and Fire/Water/Thunder/Earth damage to the whole team.

Tridon has a powerful shield, 140% defense, 35% BC and HC drop rate increase

Zenia BB Atk increase, Spark damage increase.

It just depends on what you need, really. They all do very different things. Heck, I have them all but Zenia on the same team. (I use Zenia as the friend reinforcement)
