I think they're getting there but missing big features like a high quality "Apply" workflow and next-edit predictions.
I'm working with two of my friends to fill the missing pieces as a JetBrains plugin: https://docs.sweep.dev/
That's cool that you're looking at those things. I hope we've made progress on "Apply" (and we're doing more.) And as heads-up, as you can imagine, we're looking at NEP.
