Miles has a solo as well.Pete doesn't really have a secondary solo rn.Non-stop has been a mess.If we had an ongoing like friendly neighbourhood or Spectacular then I could agree.
Also if the book is Spider-man (or even Spider-fam to an extent) then Pete should be the main guy.Again not every story but when all the issues are put together he should have the most stuff.Not by a landslide just a healthy margin.
Also the Batman comparison isn't really valid because batman is the single most over-exposed character in the history of fiction.
