Conclusion

This comparison used preconfigured sites, so the exact functions of the Drupal or WordPress site you use may differ from the ones mentioned here. However, the differences between the two programs were so systemic that the exact structure of the sites you use should not greatly change the results given here.

The truth is, both WordPress and Drupal are mature pieces of software with, I suspect, a good deal of influence on each other's development. Neither is going to have a major feature that the other lacks for any length of time, and most bloggers could probably be content with either.

In the end, your choice of one over the other will have more to do with your preferences and needs than with any advantage or disadvantage one has over the other. On the one hand, if you like as much control as possible over every aspect of your blogging, or need to manage multiple blogs, then Drupal is designed for you. On the other hand, if you are willing to let the program do some of the management for you and have relatively simple needs, a preference for navigation efficiency, and only a single blog -- or perhaps two or three at the most -- then you will probably be happier in WordPress.
