No, not really.
You're failing to understand that a character fighting a stronger enemy doesn't mean he is stronger than the characters who fought weaker enemies if the character who fought the stronger enemy also spent more time and had more difficulty to defeat the stronger enemy, especially if the character who fought the weaker enemy was even relevantly nerfed while doing it.
And I'm not even referring to Sanji and Zoro here, but to Sanji and Luffy; The douriki of Lucci and Jabura were in fact reliable as references to judge the difference of power level between them, considering how both Lucci and Jabura had a carnivorous devil fruit power for at least five years, but the fact that Luffy fought Lucci (4000) while Sanji fought Jabura (2180) still doesn't necessarily mean Luffy was stronger than Sanji, considering how Luffy's fight with Lucci was the one that took the longest time to end, ended practically in a tie, as Luffy couldn't move his body after the fight, and Luffy even received some kind of help from Usopp, who cheered up Luffy and also distracted Lucci giving time for Luffy to rise up again, whereas Sanji fought Jabura after being terribly hurt by Kalifa (as pointed out by Chopper), he defeated Jabura with much less difficulty and also faster than Zoro defeated Kaku and much faster than Luffy defeated Lucci, and was in so well state after the fight that he was able to run to Zoro's place immediately after ending his fight with Jabura, without needing to rest and without complaining about any pain.
Another example of how the power levels of the antagonists in Enies Lobby did not correspond to the power levels of the Straw Hat pirates is the fact that Franky fought Fukuro (800) while Chopper fought Kumadori (810), but in order to defeat Kumadori Chopper had to lose his consciousness, and just like Luffy he couldn't even move his body after regaining his consciousness on the ship, whereas Franky's condition after defeating Fukuro was so good that he in fact also defeated Chopper himself, and was the one who reached Robin while also beating that elephant sword.
About the comparison between Sanji and Zoro: The difference between Jabura and Kaku's douriki was not even reliable as a means to compare their strength, because it did not take into consideration their devil fruit power, and Jabura had a superior carnivorous zoan devil fruit power for at least 5 years, while Kaku had just eaten a herbivorous zoan devil fruit, and was still so bad at using it that he even failed to turn into his hybrid form in the beginning of his fight with Zoro.
The truth is that people who think that Kaku was stronger than Jabura are just bad readers.
