I find the granular reactive paradigm of Solid to be both harder to build composable pieces with, and harder to debug in a few ways. Having a render function that re-runs on updates where you can set a debugger or log is a massive thing.

Svelte has a whole host of similar and differing problems.

Personal opinion - I’d choose React today over the rest, as someone who built my own frameworks much like Svelte and Solid 5+ years ago.
