I feel I get conflicting answers when I try to research this question.
In the Anaplan Model Builder training, they say export from the Data Hub to other models. Likely because model to model import is less time, and this will make the spoke have less downtime.
However, in forums, I see people saying either one is okay. If you dont need any data in data hub, it is okay to export from spoke. No need to duplicate data in Data Hub and Spoke.
What is the official " If this is on an exam, this is the "right answer" " Anaplan answer for this?
