In comparison with guys like Thor, Captain Marvel or the Hulk spidey's powers do indeed look puny. Other people like Cap or Black Panther (although nowadays technology may shift this battle towards T'challa) while less powerful than him are always portrayed as more competent or skilled. That said, the point is different: for Peter winning as Spider Man does not mean winning as Peter Parker, one of his most consistent tropes has always been that he defeats the bad guy but there's always a catch, something going wrong with his life and ruining his day. Despite this he perseveres because he's not wearinga costume doing crazy and almost suicidal things for self gratification. He's doing it to help others DESPITE the personal cost and that's an integral part of Peter Parker (and Spider Man obviously) as a character.
