Kaku is now relative to Lucci as they are two awakened Zoan users sharing the exact same form. They've far surpassed Mr Go's feats, who struggled to put down Izo in a 2v1. Izo, who is no higher than YC4. Making Mr Go Vet-level.
No Vet-level character could ever hope to match G5 Luffy in a clash of fists or push back Zoro to any degree. Lucci and Kaku are clearly high-tiers.
But their strength is irrelevant, you can place them wherever you want. What's relevant is that Kaku is now relative to Lucci as they share the exact same power-up right down to the design. There's nothing suggesting Lucci is levels above Kaku anymore, meaning Base Zoro using hardening is comparable to G5 Luffy using hardening - especially since he overpowered a Kaku using higher-end attacks than Lucci used.

What do you think about Kaku getting the same power than Lucci in only 2 years while Lucci knew his fruit power for a longer time?
Aint that an indirect W for Kaku? (this are the only 2 that got promoted to CP0 from the original CP9) aint also that a W for Kaku (from Lucci I would expect that not from Kaku)
