With the way Oda has been treating Kid, I honestly wouldn't be surprised if he is already a low top tier
I mean the reason everyone was shitting on him so much was because of a perceived disappointment when Kid, the rival of Luffy, was overshadowed by Luffy and zoro during the rooftop. But Kid hasn't taken many Ls in wano. It wasn't so much that Kid got bad portrayal on the rooftop, as much as it was Oda just not showing us much of him. After all we only saw him use 2 attacks on kaido and then help throw big mom off onigashima.
With big mom vs kid and Law, Oda has implied that Kid is extremely powerful with him stalling big mom for all this while despite being nerfed. Yet up until now, we haven't gotten a single panel of them actually fighting. We just saw the same panel over and over again of kid and law standing by a laughing big mom.
It just seems like there's a lot of build up that would go seemingly nowhere if the highlight of this fight was kid simply making big mom cough up blood, something we saw Luffy and zoro do to kaido numerous times on the rooftop.
