We are in the middle of our migration to 3DExperience On Cloud. Now due to our "bad" V5 data storred in Enovia V5, the recommandation would be to always use "Physical Product" and not use "3DPart"

The data issue is that we have "Part Reference" with "Document Revisions" and if the document for some reason have been attached to a different "Part Reference" then it will be migrated as "Physical Product". This i understand. Clean it up before migrating. 

But we were advised to only work with "Physical Product" and not use "3DPart"
I don't agree..

2nd. What are your take on shared representation? I prefer to have non shared as default and when needed change to shared. 
Again we were advised to use shared representation. 

I do not agree.. 

What are your experiences with 3DPart vs Physical Product? Shared and non shared representation?
