The PHP community definitely has its choice of frameworks to choose from - CakePHP, Zend Framework, Solar, Symfony - but according to Paul Jones there's some that "suck less".
I don't mean to put words in her mouth, but I'd prefer to extend Laura's phrasing a bit. I'd argue that "all frameworks from other people suck". The "other people" part is important here. It sucks to have to learn how someone else wants you to work, and that's a big part of what a framework needs from you: to learn how to use it. Learning someone else's code is much less rewarding in the short term than writing your own code.
He suggests that your framework is better because of just that - its yours. You know how it works, the ins and outs of the features and how its been refined down to just what's really needed. He does point out, though, that:
Sturgeon's law says 90% of everything sucks, and the development world is no different. Almost nothing is perfect for every developer: there's always significant room for valid criticism on any project, and even the best projects are lacking in at least one vital area (and that area is different for each project).
