What each one is

The product in its own terms, so the numbers below have context.

Preact

Leader

A minimal virtual DOM framework providing React-style components and APIs, optimized for tiny bundle size and fast performance across modern browsers.

Independently observed

SolidJS

Solid is a JavaScript framework for building interfaces that emits native DOM operations rather than using a virtual abstraction. When your application state changes, it updates only the parts of the interface that depend on that state, avoiding unnecessary component re-renders.
