Nominating Hakari for worst Information Manipulation (Type 1), Homing Attack, and Power Nullification. These specifically have to do with his Domain Expansion.
So some DEs in JJK possess an effect that ensure the user's Cursed Technique is guaranteed to hit their target regardless of the target's ability to prevent attacks from landing. What the effect actually is varies depending on the CT.
Hakari's sure-hit effect in particular transfers knowledge of how his DE works into the opponent's brain. That's all it does. The info doesn't even have any sort of negative effect like Gojo's DE. The power null and homing attack also ensures that the opponent will receive the explanation regardless of if they somehow have the ability to avoid that. This means Hakari is always giving his enemies free info of how his trump card works whenever it's activated which might allow them to figure out ways to prevent or counter it.
(I'm honestly not sure whether Playtime or Hakari should take the spot for Power Nullification. Which one is worse between a power null that is very easy to counter and is nearly useless along with its user being dumb, or a power null that is actively beneficial to enemies but its user is a very smart and lucky guy who is aware of his own weaknesses? We'll have to answer this question in order to figure it out)
