Eh, not totally. For instance, the backoffice UI of Umbraco CMS was rewritten using Angular or something, and now it's just...slow. Unreasonably sluggish. I've seen other work from agencies with no 3rd party dependencies that use all this crazy JS and animations that unless you're on a top line MacBook, it's just sluggish.

I've been using the web for a long time, and while loading was slow, I don't remember UIs feeling so sluggish and unresponsive.
