There are too many unimpressive ORM projects. There's a hundred PHP frameworks and half of them decide to roll their own ORM rather than use and contribute to an existing project. So you're left with a lot of unsophisticated systems. Doctrine (PHP), DataMapper (Ruby), SqlAlchemy (Python), LiNQ (.Net), Hibernate (Java). I've used all of these a great deal (except Hibernate, I've not done all that much Java). All of these projects are sophisticated, complex, impressive. Propel? CakePHP ORM? Or just search php orm -doctrine -propel and look at the 3 dozen results. These are junk. I'll stand by that assertion. Not because they're PHP, but because they were started often as a part of a larger framework without any respect paid to the fact that an ORM is a very very hard problem to solve.
