Everybody starts somewhere, but they reach where they are now on their own, not by their daddy's help.
Jinbe started as Fisher Tiger's crewmate, but he peaked, joined Shichibukai, gained bounty, fought Big Mom, all on his own effort.
Zoro too, from low bounty pirate hunter to where he is now, thanks to his own effort.
Not the same with Sanji. Without daddy's powerup, post TS Sanji was jobbing to Vergo, Doffy, Niji, Judge, Yuen, Page One etc. He would get killed by Queen, and Queen literally called him "Judge's son".
Now thanks to him being Judge's son, he can defeat Queen, survive Saturn and Imu. While again prior to that, he jobbed to the likes of Vergo and Doffy.
So yeah, Sanji himself (without daddy) career ended with Vergo level. He is where he is now only thanks to daddy power up.
