He needed to care more about securing the secret of his identity (like not show his face to any other hero, or share his name), and needed to be far more competent in Homecoming, I'd appreciate him more if these problems weren't available in this world.
I don't care to watch more MCU after losing the best character and the second best one in this world, maybe I'll watch the Asguardians of the Galaxy vol 3, Thor 4, and possibly Black Widow prequel, these don't need Spider-Man so I'm not going to cry over the damage done.
As far as movie versions of the character stand, the Maguire one is the most competent and responsible one, so he's definitely the best. His Peter needed to be more confident and outgoing than the overly shy guy he was to be a more faithful adaption.
