Maybe not worth much, but the one Ember app I use routinely (that I'm aware of) is YNAB. The startup is slow, the payload obscenely large (over 3MB) for basically 2 different views, a handful of modals. It has odd UI issues occasionally that appear related to data-binding of some sort (tabbing through a field will sometimes cause an associated modal to freak out). Plus the URLs are useless.
I don't know how much of that is Ember and how much is implementation, but I assume their developers are smart enough.
What value did Ember bring to the party? It seems to have made what appears to be a simple thing (at a high level; not that there isn't plenty of effort involved in little bells and whistles here and there), complex and slow.
For me it's like that old saying about Art. I may not know exactly what I'm seeing, but I know what I like, and that isn't it. When your framework has basically the goals as ASP.NET v1 but the code looks worse, that's a major step in the wrong direction. It's been over a decade. This doesn't feel like progress.
