I took a look at Datastar, and pretty quickly realized I really don't like libraries which try to do so many different things. The surface area of the API is way too big. htmx is already too big for me, I tend to reach for mostly vanilla-only or small vanilla-adjacent solutions I can either write by hand or import. But as I've been experimenting with htmx (including its very good extensions API), I'm realizing it's in a pretty good sweet spot overall.

I'm very excited about htmx 4.0 and sounds like things are headed in a promising direction.
