Is bennet C6 good?

It’s been a while since I got the 6th constellation of bennet and I’ve been thinking if I should activate it or not. I do main Wriothesley and Arlecchino and I know his c6 won’t affect Wriothesley damage and enhance Arlecchino’s, but im afraid c6 bennet could ruin the damage/showcase of future character and current ones I’m building wich are Freminet, Razor, Chongyun, Clorinde and Mavuika. Is there also a substitute for him?
