Ask HN: What's a Good SMS App for Android?

Now that Signal is removing support for SMS, I'm anticipating an exodus as Signal users search for alternative SMS apps. Does anyone have any recommendations?

I don't want to use the default Android SMS app, because apparently it will soon support sending and parsing iOS fallback messages (i.e. 'Liked "..."'). I just want plain, standards-compliant SMS, with no risk of accidentally sending fallback messages. Plus, I don't agree with the notion that Apple should be able to bully others into recognizing their SMS extension features.
