In my opinion, ripple is not a reliable coin. I think it is not giving hope for the future. Its price is just pumping and dumping, nothing much.
On the other hand, I like Stellar's price curve and I think it is a promising coin.
I also don't like ripple but when it comes to a comparison between xlm and xrp, I can say ripple in this case. I think xlm is now in a hype. That's why.
