Should I awaken 4 star venom or 4 star Medusa. Which is better

Thanton

Hey guys I am at level 37 and I got an awakening gem of cosmic. I am confused now about whom to awaken. I got Venom and Medusa as the two best cosmic champs. Now please suggest me whom should I awaken.

I'd go for medusa because her awakened ability is a chance to auto block.
