This advice is especially for Wanted and Stark:
Run the OG Versions first to build a base, for like 6 months, than you can try it’s black counterpart.
Emperor Black I’d imagine would also profit from a longer Emperor run.
Khan Black on the other hand works differently.
I never heard that you should have run Khan first.
EG AEONs description mentions running KB and Alchemist twice before running AEON. But not Khan.
I’ve ran KB after 3 months of SC. Stage 1 with the results I wanted. (Out of desperation, but that’s another topic).
For most Artisinal titles, it’s recommended to have more experience with SC titles.
There’s no concrete recommendation like run Limitless before RoM or Alchemist before RoS.
