I like ALL the Spider-Women... however a most should be given new names and/or themes.
Jessica Drew should be the one and only Spider-Woman
Arana should be the one and only Spider-Girl.
Julia should be Arachne or Arachne-Woman.
Cassandra Webb should be the one and only Madam Web.
-her grandaughter Charlotte Witter should be a mutant who can absorb other's powers.
Silk is fine as silk.
Ghost Spider should keep that name.
Mattie Franklin should be given a new codename - Recluse.
