Which grocery store is actually the cheapest?

It depends on where you live, but discount grocers like ALDI, Walmart, and Lidl usually come out cheapest for a typical cart, while full-service chains and specialty stores tend to cost more for the same items. The honest answer is that the cheapest store is the one that is cheapest for your specific list, since prices vary by item and by region. That is why comparing your actual basket beats trusting a general ranking.
