Please Advise on the Best Forbidden Jewel Choices for a Corrupting Fever Build

I am currently playing a Corrupting Fever build as a Champion.

When I look at similar builds on poe.ninja, I notice that most are using the Gratuitous Violence Forbidden Jewel. I understand this is to improve map clear speed due to its higher explode damage compared to Haemophilia.

Now, here's my question.

If I want to reduce Boss Kill time with the same build, is there a Forbidden Jewel that would be more suitable than Gratuitous Violence?

"Headsman" is the only other choice and I doubt it's much better since you free up a glove slot with "Gratuious Violence".

That being said, CF champ excels at one thing and that is mapping with high packsize. I wouldn't use it for anything else tbh.
