A quick look around the internet, the only source I could readily find an energy density comparison showed the sodium ion battery had an energy density of roughly half that of lithium ion. So a 20% cost difference really disappears when compared to needing double the amount of battery for the same amount of energy storage. Not going runaway is a benefit, though.
