I've been doing a small project in SolidJS recently and really enjoying it. It is a lot easier to reason about than React. My only complaint is that the router is kind of alpha and a moving target, so the examples are now out of date with the latest version. Also, like most open source projects, the documentation is lacking in a lot of ways. That said, if you know React and you're not doing anything too complicated, I highly recommend it.
Is the router you are using solid-app-router [1] ? Have been working with it for last few months and it has been generally stable (my usecases are not particularly complex though).
The docs for the solidjs core has also massively improved recently.
