Anyway you can take the capsule to a lab to find out what type of fillers in both products, the percentage of those products, the percentage and amount of EPA and any DHA in the capsules. It would be great if they could do an oxidation test. I am sure many on this board including myself will be happy to fund this initiative.
One more thing to note about smell of genericV versus off the shelf omega 3. When I say they smell the same I mean in level of intensity of the smell. However, each smells like a different type of fish. If I had to guess I would say maybe anchovies for genericV not really sure what fish off the shelf is but if I were to venture a guess I would say salmon.
