mid high imo sounds perfectI actually think Sai seems like a beastDon't know why, he just seems really strong. And yeah, the resemblance between Ideo and Lucci is a bit intriguing! But anyways, his punch blew a Giant off the platform. At least he has some decent strength. Funk Brothers, they suck.
I'm not if I agree on your Zoro vs Sanji thing, but I don't disagree either. I honestly don't know where to place them. Sanji just hasn't done anything to seem as badass as Zoro yet. But I don't think he's that much weaker than Zoro. But sure, mid-high diff sounds plausible. At least until we get to see both of them in some serious fights. Zoro will always be stronger than him though, imo. As far as the people in Block C, I'd say Sai would be his equal right now. I think Anyone under him, Sanji would be able to handle. And then next chapter, Ideo one shots Sai xD
as for sai i did some researching, i thought he was the vice leader and the other guy that the suck brothers took out was the leader but its the opposite i think sai takes out the suck brothers (god i hope) chinchao takes out the mexican hunter (i love how i said his name in a previous post and now i forgot it lmao) and lucy tries to cover his face more oh yea and ideo and sai take eachother out
