In the Nature Portfolio, there exist two series of journals lower than the 'Nature branded' ones: npj journals launched in 2014 and Communications journals launched in 2018.

However, it is not quite clear to me what their positions are supposed to be. Of course the npj journals are less multidisciplinary. But this aside, which group is higher in the ranking?

The editorial expectation might differ from the real recognition by the readers (e.g., the Communications journals are younger). If this matters at all, I presume knowing the editorial expectation would also be helpful.
