I disagree, both Vue and SolidJS share the same underlying signal mechanism. Vue hides it a bit more, and has different default primitives, but they're both doing essentially the same thing under the hood. In both, you can think of a component as an entity that exists continuously for as long as it is mounted, and connects sources (i.e. signals) to outputs (i.e. HTML values).

React, on the other hand, is very much focused around the `UI = f(state)` paradigm, where the `f` (i.e. the component/render function) gets called afresh every time the state changes. You can avoid that somewhat via memoisation etc, but this is conceptually an optimisation rather than how the framework works.

The JSX vs SFC aspect is still significant, and SolidJS definitely tries to use some of the affordances that React developed initially. But the core idea in the framework is much closer to Vue than to React.
