You panicked and edited your message?
Mihawk even admitted Old WB > himself, even after WB was stabbed, Sengoku said WB > Mihawk. Healthy prime WB and Mihawk Haki difference is a big difference just like Joy Boy and Mihawk Haki difference.
Whitebeard is canonically superior to Mihawk due to "title scaling" , you ZKKclowns like title scaling only when it comes sword skill title, why you forget about the real power title which is WSM? WB was declared strongest when prime Garp and prime Rayleigh was around not only WGS Mihawk.
The point that made you panicked Mihawk or Zolo using Haki even prove my point because they will use 2nd tier weaker Haki than 1st tier Haki like Joy Boy, or EoS Luffy, or WSM WB's Haki.
The only 1st tier stat about Zolo and Mihawk will be sword skill, not Haki level. So ZKKfans talking about Haki is pure desperation when we know Sanji will also have that same 2nd tier Haki that Zolo will have.
1st tier Haki users: EoS Luffy, Joy Boy, Davy Jones, Prime WSM WB etc.
2nd tier Haki users: EoS Zolo, Mihawk, EoS Sanji etc
That difference won't change.
