Who is better to use? Black Cat or Kraven?

I have both characters as 5 star champions, both unawakened. Take into account, who needs their signature ability more, who is easier to use, and who most likely to benefit from a high rank

Kraven is a weird one you need awakened ability and the enemy to cooperate with you

On the other hand black cat has great utility easy access to damage and is the overall better champion
