Fast prototyping is remix's biggest strength. It is super easy to get going with the routing and implementing all the SSR loading for the routes. The handling of forms, errors, and loading states also is beautifully easy.

I initially only wanted to use the authentication but decided to opt in for the Postgres Storage and the Storage as well. Row-Level-Security really makes life easier.
