Definitely disagree. No one, not even King is tanking his attacks without damage when Zeus makes BM scream in pain with Enel producing volt Zeus can't evem dream off.
His observation Haki surpasses that of Katakuri in many parts. His only short coming are physical stats which are buffed accordingly as the story progressed.
Still, see no problem with him on Skypea fighting them 1v1.
Big Mom was tanking Zeus' attack before she was skinny tho. And again, powercreep already took a huge part in it but we also have several instances of characters enduring said lightning attacks without going down after 1-2 hits. G5 Luffy was even catching lightning mid-air as if it was nothing. Marco can evade Kizaru's light attacks. Light speed >>>>>> lightning attacks. Heck, there are several sublevels of speed between LS and lightning speed before you reach the former.
Enel's observation is better in range but Katakuri has the upperhand in 1vs1 due to FS, if their distance starts at 50m.
Again, lore-wise, Enel sure is stronger than people give him credits for but when it comes to hypothetical match-ups, we have to include feats in here. Otherwise there would be threads like Alabasta Crocodile vs Doflamingo/King/Katakuri/Marco and so on. And feat-wise, YC1 simply scales to much better stuff bar firepower.
