There is most certainly a case for it. The ongoing integration in the existing financial system is a big plus because they seem the first to really bringing banks onboard. For consumers, getting faster and cheaper payments is always a plus.
I am also looking at Stellar which also seems to aim at integration in the existing financial system with an open source network governed by a foundation in Germany, accessible to all. Stellar will open an airdrop soon (Bitcoin account with a balance + Facebook login outside of USA/some other States) is sufficient to join. I guess Stellar needs more attention but I always welcome free entry.
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.
