Does Knightfall Vader Have More Force Strength Than Sidious?

Force-only.

Is Knightfall Vader stronger in the Force than Palpatine?

Legends-only.

Forgot to clarify.

More raw power, yes.

Does that mean he wins a Force exchange? I just don't think he has mastery over the Force to a degree where he could take such a contest.

He'd certainly make Palps sweat, but no he wouldn't win force only

Depends on the source you go by

yeah for sure, he is the Chosen One after all, but can he control that power is the real question, Sidious has him beat there.

He has more force strength than anyone.
