In 2014, Nature collaborated with parters and launched npj, and they state "Nature Partner Journals adopt a modified set of Nature editorial standards". In fact, relatively high impact factors are observed in these "npj" journals but these journals are branded with "npj (Topic Name)" rather than "Nature (Field)".
What's more, the journals like npj Computational Materials (IF~9) and Nature Communications (IF~12) are slightly comparable in terms of the impact factor.
So my question is, do "npj" journals have a comparable reputation to other Nature derivative journals like Nature Materials, Nature Physics etc.? Basically can I say I published in a Nature journal after publishing in npj?
