Multiple Body part file vs. Assembly

Hello,

I am an industrial designer creating a tablet stand for a mechanical engineer to review. I created built multiple-bodies in one part file and then brought it into an assembly to add other parts such as the pcb, lcd, USBs and other connectors. I build nearly all my SW files as multiple-body part files because I think it makes a more agile model i.e. easier to modify all parts at once as each part references another. However my colleague recently suggested that engineers may prefer multiple part files instead.

My question:

Is it considered better professional courtesy to have built all of the stand as a multiple-body (less than 7 bodies) part or should I rebuild each part separately thus sending an assembly with multiple part files?

Thank you for your professional insight!
