Hi @Foxtail - Good question. I’d say unless all of the components are already rounded off, you may also want to check out this post where I shared how to use V-Ray Materials to round the corners in the render without adding any new geometry to the model.
Up to you which you think works best for your needs. Doesn’t seem to be a huge difference in size so I don’t see any performance issues to worry about. For me, I tend to avoid having duplicates of models as if one changes it’s hard to track that they all get updated accordingly.
