Which is faster to develop in, Laravel or Symfony?

Laravel, for most teams and most projects. Laravel optimises for developer productivity with convention over configuration, expressive syntax, a gentle learning curve, and the broadest set of first party packages so common features are a composer require away. Symfony optimises for explicit control and flexibility, which means more configuration and more decisions, trading some speed for structure. A Laravel team typically ships a standard web application faster. A Symfony team gains in projects where the explicit control and component assembly genuinely pay off, usually large, long lived, structurally demanding systems.
