Is +Defense or +Evade a better Leader ability?

In Galaxy of Heroes, some characters have Leader abilities. Some of them have the same type of bonus but for different aspects.

For instance:

• Talia and Daka will both provide Nightsisters with some bonus. But what bonus is more powerful? Evade (Talia) or Defense (Daka)?

• Luminara's Evade or Eeth's Defense?

What I'm looking for is not a opinion on what power you prefer :) I want to know what power will result in a better benefit for my team.

I.e., "Defense is useless, use Talia to evade better" or "Eeth's Defense bonus is too low, use Luminara instead."
