Are there any good non-Prolog or Prolog-based logic programming languages ?
Who has or any good experience with it?

I highly recommend The Reasoned Schemer, by Dan Friedman, Oleg Kiselyov, and Will Byrd. It introduces miniKanren, a small (three core operators) logic programming language built atop Scheme. It's a joy to use, particularly with the matche macro that allows unifying pattern matches.
Answer Set Programming is an extremely powerful logic programming paradigm. I've had a lot of success with the clasp/clingo answer set solver.
There's also pretty fast miniKanren implementation written in Clojure, called core.logic.
There are also a few tutorials on using it:
