>I'm not the only one who think Safari is a joke compared to the competition.

How does that opinion survive reality, e.g. Safari being the first browser to reach 100% ES6 compliance?

So? All browsers still have Flexbox issues. Here are Chrome's:

ES6 has very little to do with keeping up with Web APIs. See https://platform-status.mozilla.org/

Notably Fetch API and WebRTC for my use-cases.
