You guys are viewing this from a powerscaling point of view which obvioulsy doesn't matter as much to Oda as it does to the people here.
Zoro and Sanji are main characters we have known for 1000+ chapters, their fights always get the most focus after Luffy's.
What do you think makes the most sense, the most importants fights of the final saga against the World Government will go to some side characters or to main characters Oda spent 25+ years focusing on ?
Narrative > Powerscaling, Oda will make Eos Zoro and Sanji as strong as they need to be to take down admirals, it's obvious.
