@rudimk Thanks for liking it.
I opted for RethinkDB because of its native admin section and the ReQL game.
Also I love it, when it shows the DB read/write visuals.
On your question, I'm actually biased as I have used ReQL only.
But now looking on Thinky, I won't use this because it gives me a feeling of mongodb models / mongoose and all.
I think you are open on query choices when you are going with raw ReQL.
