Which crypto-currency protocol would be best for a real life, local currency?

[Elwar]

If a small town were looking to create a "my town cryptocurrency" where they use it in all of their shops, salaries, coffee, government, etc. which protocol would be the best to replicate?

As big of a supporter of Bitcoin as I am, I understand that you can use bitcoins for this. I have lived on bitcoin and paid for coffee with bitcoins, but I imagine some of the alts may have currency advantages over bitcoin like fast confirmation times and other features that would work better as a localized currency as opposed to a world currency.

Any thoughts on this?
