Dave Rolsky wrote a [fantastic article](http://blog.urth.org/2008/12/the-many-axes-of-software-development.html) on the many different criteria on which you can choose your software to use. For example:
> # Easy to integrate – Some libraries are designed to be integrated with other modules (Catalyst), some want you to embrace their world (Jifty).
> # Complete – Some libraries come with a complete solution (Jifty) and some require you to put together a bunch of pieces into a whole (Catalyst).
Which is better? The answer, of course, is “it depends.” Is the project for in-house use, or will it be distributed? Is it a one-off, where the base install will do most of what you want? Or are you likely to want to extend beyond those constraints?
Most importantly, Dave points out:

The extension of that is that many people may not even have thought about what their priorities are. Consider how often you’ll see a question, such as at Stack Overflow, that asks [“What’s the fastest way to do X?”](http://www.google.com/search?q=site%3Astackoverflow.com+fastest+way) Most of the time, the querist hasn’t even thought about that “fastest” part; it’s just assumed. (For that matter, that’s like assuming that the most important part of a new job is how much it pays, but that’s a topic for [another blog](http://theworkinggeek.com/).)
Make sure you know what your priorities are. Question your assumptions. Your project will thank you for it.
