How does native ES6 performance compare with the performance of ES6 compiled into ES5?

Because right now there isn't enough cross-browser ES6 support to be able to use it reliably with compilation; given that the compilation procedure is easy and relatively pain-free (at least until you see the horrifying code that Babel produces when you ask it to transpile generators), I'm wondering how much of an issue ES6 performance is in the real world.
