I dont care what you think they are, i talked about how oda sees them, the ones who draws the manga. You can deny/be other opinion that till EoS doing your little RPG math and counting haki lightning, i am chilling as i can read a picture book with pictures

Its luffy and zoro who fought to see was stronger
Luffy and zoro who were supernova
Luffy and zoro trained by legends (also coby)
Luffy and zoro unlocked haki pretimeskip (also again coby not sanji)
Luffy and zoro have advanced hakis (even more damning once again coby not sanji)
Luffy and zoro have people they are aiming to surpass who are rivals in mihawk and Shanks nothing for sanji again
All of this is STRENGTH RELATED
Unlike wings which giants and gaban himself debunked it being about strength
But sure lmfaoooooooo
