Hickman's fantastic four run.
Whenever hickman did stuff for marvel he always had 2 books running concurrently whose events were interrelated. One book would be a "forefront"/"mainstream", and one would be "underground." or in other words one book for what the mainstream 616 universe characters were aware of what's going on, and one book for what's really going down behind the scenes. That's my interpretation anyway. Hickman probably explains it better in one of his past interviews.
For marvel's first family he had
Fantastic Four and FF(Future Foundation)
then for Strategic Hazard Intervention Espionage and Logistics Directorate he had
Secret Warriors and S.H.I.E.L.D.
then for Avengers he had
Avengers (Vol. 5) and New Avengers (Vol. 3)
