> It just basically does everything React does but better

SolidJS still has some major pain points; the one I found was not knowing whether a prop was a signal or needed to become one. The type system doesn't help much. In React, you know for sure that if your reference changes, the component reading that reference as a prop will re-render. In Solid, it's less clear whether the update will be observed.

Amen. Data flows down. That, to me, is one of React's biggest strengths.
