I personally have only had substantial experience with react (and its hooks), but the replacements for hooks in this library look very exciting to me, though I'm not sure I fully understand them on a first reading. One thing that react hooks require is the placing of hooks at the top level of a function, which precludes dynamically creating hooks in a loop, or lists of effects. While usually there is a way to achieve whatever you're trying to achieve anyway, it's still a bit of a restraint on what you can write with React. I haven't tried Solid yet, but if its hooks are nestable and composable as the Reactivity page says, then this could enable some patterns that were previously impossible with react hooks.
