I would prefer litecoin, after all he is a brother of Bitcoin, and I like it much more than an overvalued ripple. At the same time, it has great potential for growth.
both are just as good, you will get many benefits if you invest in both. if you invest you will get more opportunities because they will be profitable or even both will be profitable. in the future they will get better because they have great potential. Ripple and Litecoin have their respective advantages and both will complement each other.
