I never heard a good argument on why Enel isn't YC1
"He got beaten by Skypea Luffy" - Type advantage and the entire fight was Enel being caught off guard because he didn't know what rubber was, as soon as he knew his trident could hurt him he started getting the advantage
"He would be fodder in the new world" - He's shown to have an amazing observation Haki and his agility is insane, he can oneshot most people before they even notice it
"His stamina and durability sucks" - Enel got up again right after his fight with Luffy but he was already flying to the moon so he didn't want to deal with him anymore, and let's not forget anytime he gets close to dying he can just restart his heart as we've seen before
The worst case scenario for him is that he's a big glass cannon, but he hits so hard and barely anyone can even touch him due to his speed and observation haki
And btw, this is pre-TS that we're talking about, if Oda buffed Crocodile and Lucci so bad after the TS I can't even imagine how much stronger Enel would get
