Forgive me, I misinterpreted your question. I do not see any conclusive evidence yet that there is any superiority of either naturally acquired or vaccine mediated immunity. That will no doubt become clearer with time. I'm still on the fence on this one, myself.

Persons who have symptomatic CoV2 are indeed capable of infecting others, just like any other infectious disease. There is a widespread suspicion that they are less infectious than non-vaccinated cases, but I haven't seen any hard data to prove that.
