IMO, Dimentio has no ways of killing Bill. The only way to kill the dorito is by getting him in someone's mind, then deleting him. Dimentio never showed any memory altering powers and doesn't have any equipment to do the job.

Dimentio making Bill commit suicide isn't guaranteed to work. Also, by that logic, the Dreamcaster can kill Dimentio in a Death Battle by hypnotizing him into comitting suicide, despite the power differences.

Bill has more ways to kill Dimentio too. Using his Madness Bubbles, he can make Dimentio mentally insane, causing him to do random stuff like screaming and running in circles - in this state, Bill can easily finish him off. Bill used a ritual to make him return after erasure, which rules out Dimentio's finisher of deleting him.

This and many many more reasons is why my vote is on Bill Cipher.
