Which has the better ORM, Eloquent or Doctrine?

They take different approaches and each wins for different needs. Eloquent (Laravel) is an active record ORM: expressive, fast to write, and excellent for most web applications, with the tradeoff that the model carries persistence logic. Doctrine (commonly used with Symfony) is a data mapper ORM: more explicit separation between domain objects and persistence, which suits complex domain models and large systems where that separation pays off, at the cost of more verbosity. For most web applications Eloquent is more productive. For complex enterprise domain models where strict separation of concerns matters, Doctrine's data mapper approach is often preferred. Note Symfony can use Eloquent and Laravel can use Doctrine; the pairing is conventional, not mandatory.
