We talk about this a bunch in https://www.youtube.com/watch?v=qwIyenCaSXk

The TLDR is:

* We like templates, and were able to implement a more efficient algorithm using them (even more than the recent improvements in Babel).

* Compatibility is important to us, so HTMLBars was going to be a much better transition story for Ember 1.x than JSX.

* We prefer an HTML-centric templating story (copy/paste valid HTML and it works) over an XML strategy that requires camelCasing, className/htmlFor, etc.

* We optimized Glimmer for a hybrid (rerender + subscriptions to the model or service layer) model that can opportunistically avoid work based on knowledge we have from the whole stack.

Fair enough, but I would argue JSX is just as "HTML-centric" as anything Ember has implemented, so long as we agree "HTML-centric" means, practically speaking, "not HTML."

What I mean specifically is that if you copy and paste some valid HTML from inside a body tag, it will work.

That is an explicit non-goal of JSX, and it shows.
