On the fence about my team

I have pretty decent team: 4 star legendary suicide squad Harley Quinn with 69000 threat, 3 star gold master thief Catwoman with 26000 threat, and 3 star gold dark supergirl with 19000 threat. But I just got 3 star gold hush and I’m thinking about replacing supergirl with him but am hesitant cuz then my whole team would be agility and I don’t know if hush is better than dark supergirl. Thoughts?
