Anyone have any clue when we'll see this land in Safari?

Probably at WWDC, between June 13 and June 17.

Likely in the developer previews that they release during WWDC then available to consumers in the fall.

Is ES6 native much faster than transpiled?

Here's a chart: https://kpdecker.github.io/six-speed/. Often the answer is "not yet". Transpilers convert the code to ES5, which has benefited from six years or optimization. New ES6 features will take some time to catch up.

From my limited anecdotal testing no. In fact it may be slower. This is a good view of this: https://kpdecker.github.io/six-speed/

However... the potential upside is size. Native code will usually be smaller, which for a web client is a win.
