I think it shines in the way it handles transactions. The speed is fast enough to be usable for commerce - transactions are quick enough to confirm whilst a user is at a checkout page. The transaction fees are also low enough to make the coin viable for low value transactions. You can't use Bitcoin for that any more, the transaction fees are too high. For this reason, to take advantages of SuperCoin's strengths, I'd like to see plugins to allow SuperCoin to be used as a payment method for the most common shopping carts.
