At $dayjob right now I'm using remix+supabase (although the supabase part is going away, but we're keeping postgrest). I have to say I quite enjoy it. DevEx seems good (although we've added quite a bit of our own logic on top). Performance is too early for me to tell. For my personal stuff I tend to do more app-like things, so SSR/SSG is not that useful to me, and I tend to go with pure react+redux. But I might try svelte when the new version comes out, it solves a lot of my issues with it.
