Which one to choose, which one is better of the two ElasticSearch or Spinhx?

Question

elasticsearch

I want to choose one (the best) of them, and start learning.
Useful for working with the framework.
I just now found out that they are cool things, but I have to choose one.
Everyone has their own pros and cons, so when I say the best, I mean optimal,
and optimal is when there are more pluses than minuses.
