Fair enough - that doesn’t shine through on the screen, although it’s obvious that she’s more powerful than her screentime warrants.
I didn’t grow up on the comics in depth, did get a bit into the ‘bigger’ stories (x-men, Spider-Man, Iron Man, etc). But dived into a lot of the backstory since I’ve started loving the MCU. And I can’t think of any indication that SW is amongst the most powerful heroes in the MCU, let alone across Marvel. Usually Thor, Captain Marvel, Dr Strange, Hulk (even though he was super lame in Endgame) are the top MCU heroes (with Jean Grey, Silver Surfer, etc) get listed as the top heroes.
But I wouldn’t be surprised if the comics tell a slightly different story!
