He's confident and willing to show off a little, but still self conscious enough to care about what other people think of him such that he's constantly trying to figure out what would make him look cool.
He's got a much stronger desire to express himself, which you can see both in his art as well as in his desire to go to his public high school instead of the magnet one that his dad wants him to go to. Peter, by comparison, didn't desire to express himself as much as he wanted to avoid getting picked on by people like Flash Thompson. Peter's innate trait, at least prior to getting bitten, is timidness whereas Miles' is braggadocio.
And the character development each undergoes is fairly different too. Peter learns to stand up for himself and see that he shouldn't be afraid of doing the right thing even though he might put himself in danger or it might be difficult. But Miles learns a lesson more about the kind of person he wants to be, learns that expressing ones' self isn't just about being loud and brash but also about the substance of what's being expressed. When Uncle Aaron dies in the movie, Miles' take-away is that he should use his talent to its fullest, not just to gain the approval of others.
Miles' story in spiderverse is that of someone with a lot of talent who doesn't have the formed identity to direct it towards something good. Peter's original origin story is that of someone who is weak and timid but, when given power greater than those who push him around, learns not to abuse it but to use it for others.
