I agree on Stellar (which is in fact a fork of Ripple (2014)). However, I sold off my STRs about a month ago, as I was getting some fear of heights after the sharp un up.
What I particularly like about Stellar is that it is built upon a distributed open source Internet protocol and that it does not allow freezing the currency (as far as I know).
What is also worth noting is that, over time (though very slowly), the amount of XRP will decrease, whereas STR has a 1% p.a. inflation factor.
