Unfortunately, there really aren't that many better. Full transaction privacy (addresses not visible to public + amounts not visible to public) does not exist in any of the top 10.
+ offline transactions should be possible (allowing sync with the chain whenever), but also I do not think any have that.
A good crypto-currency is like cash, with a nice physical gauge theory (allowing offline transactions) guaranteeing security + any transaction processing rate.
Every single cryptocurrency now is still a research project first.
I'm having trouble seeing how you could have offline transactions that prevent doublespending. Could you expand on "nice physical gauge theory (allowing offline transactions)?"
If you have a good idea here, it might be possible to implement as a second layer on a chain with smart contracts.
That title might be misleading; the doc is just about generating transactions without the sender and recipient needing to engage in an interactive protocol. It doesn't address double spending.
