No
Firstly, it's not established whether Marco was the First Division Commander at that time since we know divisions are subject to change. Whether he is or isn't doesn't make him stronger than Oden.
Secondly, Oden has shown that he's far more stronger than a young Marco. Sure Marco had his DF, but Oden had Haki. He's getting sliced the fuck up. Garp swatted away Marco with Haki, Oden is doing the same but with his swords. Slicing Kaido is a major W so Oden replicating that feat on Marco? Lol
Thirdly, I pray to god you're trolling because you outright just denied what Oda established himself. Oda said the ranks aren't based on strength and yet you dismissed it and said 'Nope it doesn't suit my narrative that those are strength indicators'. You can't honestly treat WB's crew like Big Mom's or Kaido's and somehow assimilate the fan made concept of "YC1, YC2, YC3 etc" into WB's crew when Oda himself provided evidence that contradicts your stance.
Sweet commanders have the same rank
But in BM crew, the oldest can order the youngest. That's why daifyku can order Smoothie
Oven can order people stronger than gim.
That's why Pero could handle stuff with more authority than even Katakuri.
Calamities have the same rank
Each crew has different stuff
The rank int indication you are equal
There has never been " first commander... 2nd commander " level
Manmade. It is commander level
The strongest commander is just stronger than the rest of commanders in the crew.
Kata strongest of BM pirates
Oden was strongest till he left ... marco became strongest of WB pirates and Ace was gonna be strongesr of WB pirates after WB Death if he remained alive
Benn RH pirates
King B pirates
Shiryu (currently stronger than Burgess) strongest of BB pirates
