I'm starting a new project with symfony which is readily integrated with Doctrine and Propel, but I of course need to make a choice.... I was wondering if more experienced people out there have general pros and/or cons for going with either of these two?
Thanks a lot.
Thanks for the all the responses, useful stuff. There's no truly correct answer to this question so I'll just mark as approved the one that got the most popular up-votes.
I'd go with Doctrine. It seems to me that it is a much more active project and being the default ORM for symfony it is better supported (even though officially the ORMs are considered equal).
Furthermore I better like the way you work with queries (DQL instead of Criteria):
<?php // Propel $c = new Criteria(); $c->add(ExamplePeer::ID, 20); $items = ExamplePeer::doSelectJoinFoobar($c); // Doctrine $items = Doctrine_Query::create() ->from('Example e') ->leftJoin('e.Foobar') ->where('e.id = ?', 20) ->execute(); ?>
(Doctrine's implementation is much more intuitive to me).
Also, I really prefer the way you manage relations in Doctrine.
I think this page from the Doctrine documentation is worth a read: http://www.doctrine-project.org/documentation/manual/1_2/en/introduction:doctrine-explained
To sum up: If I were starting a new project or had to choose between learning Doctrine and Propel I'd go for Doctrine any day.
