Was Sanji stronger than Zoro after getting his raid suit? Or was he just way weaker than Zoro before that?

[Warmmedown]

Zoro did better training during the timeskip. He fought monkeys and got repeated Perona-assisted zenkais (Sanji's probs jealous, but he doesn't realise he would've been finished off by the blood loss). Sanji just frolicked around and occasionally fought? Isn't that right? He just got better agility than Zoro, but he fell behind otherwise. Then the raid suit brought him up to non-Asura Zoro's level? Or was he already near Zoro's level post-skip, then got a raid suit and overtook non-Asura Zoro?

This.

Zoro King of Hell > Asura > Sanji > Zoro

is how I’m seeing it right now. Zoro can use Advanced Haoshoku for some duration now, he should be a good step ahead of Sanji’s top power. Sanji’s Haki is still lacking. There’s no shot that he could permanently wound Kaido.
