What Marvel comic has been ongoing for the past 10 years?
Amazing Spider-Man (well, kind of), Deadpool? (Different series / crossovers) X-Men (a team that changes) Wolverine? (He dead, well was, Old Man Logan count?) X-23 (cancelled to bring back Wolverine)
Marvel is not in the business of ongoing series anymore. I don't find it a good indicator of popularity.
The only one I don't like is Spider-Gwen because she's based on a dead character.
Miles is interesting now that Secret Wars Vol. 8 or whatever basically killed off different universe's. I think there is room for multiple Spiders.
Ms. Marvel is a good, different story. It just may take a while to become more popular. Newer readers.
