Nothing really compares to Bitcoin in terms of what you already stipulated. The 5 confirmation transaction irreversibility is not something that shipcoins can match in their lifetime. Compared with other shipcoins you will think that your coin or token is secured after a tens of thousands of confirmation only to find out that it can be reversed like in the case of Ethereum. If it goes to zero then it is still stonger than their memecoins that stays at zero.
