Not really? Sanji without the Raid Suit is fighting a YC2 opponent that probably isn’t that much weaker than King who’s a YC1
Now I dunno if you think Oda plans on sidelining Sanji while every other strawhat continues to get power ups but I think it’s pretty obvious that Oda is going to scale him up to that level
EOS Luffy > everyone
EOS Zoro > Roger (he’s a swordsman), Mihawk, Shanks, etc
EOS Sanji > Kizaru, Greenbull, etc
Mind you, people can be in the same tier and still be weaker than other people in that tier. Just like Kaido is stronger than Shanks yet they’re both Yonko
