Under $5 mackerel comparison

Mackerel under $5 Trying to determine a budget friendly tin of mackerel that comes out on top. Rules were simple, Mackerel in olive oil, thats it. What sets one of them apart from the rest? Credit must be given to King Oscar for it being the most easily available! The OG has been one of my favorites for a long time.
