way faster actually. (RoR dev for several years here). You have zero-config user account system and drop-in admin panels (zero config) here too. more precise: you just code up templates and declare that you have data (mongo being schema-free helps in this case) and code up interactions with a few lines. done. with stuff like auto-form and other goodies, a CRUD SPA with batteries included is done in a few minutes, ready to run. But don't dare to dabble with correct deployment, testing or stuff like that, waste of time.
