His entire point was that the world needed Spider-man and that he had to fill his shoes and make them his own.Now he is just that,Kid Arachnid who is popular because of the fact he took Peter's mantle and has a game.Their are so many POC characters they could push who are much more suited than Miles.
He is also nowhere just as good as Spider-man is.Not because of who he is but because how long he's been at it.Peter has been doing this for decades(both in comic continuity and in real time).Miles has had only 2 years.One day he will be,sure.But he's nowhere near that point right now.
As mentioned in the original post.Spider-man in his first decade had an iconic supporting cast(MJ,Gwen,May,Jonah)and villains(Green goblin,Mysterio,Doc ock,Lizard,etc there are way to many to name here)so memorable moments(the spider-bite,uncle ben death,MJ you just hit the jackpot,gwen death etc way to many to list here).Miles has had a fluctuating cast with no good supporting cast(besides Pete's) and villans(Besides Pete's) with no memorable moments.Even though miles has so much more exposure than Pete had back in the day.That should tell you all you need to know about Miles.He's okay but not even close to Pete
