I know this is a thing of taste, but have you considered a syntax closer to SolidJS's approach? Something that feels a bit more vanilla JavaScript, where signals are just tuples with getter/setter and you use JSX instead of template strings and components are just plain functions?

For comparison, here's how this example would look:

  import { render } from "solid-js/web";
  import { createSignal } from "solid-js";

  function Counter() {
    const [getCount, setCount] = createSignal(0);
    return <button onClick={() => setCount(getCount() + 1)}>{getCount()}</button>;
  }
  render(() => <Counter />, document.getElementById("app"));
