Which is best WordPress or Drupal ?
WordPress: blogging (obviously!), relatively simple publishing and content management. It is best in situations where they are fairly straightforward relationships between people and the content they are producing.
Drupal: a good hybrid solution in which, say, your client needs to manage public content in a “traditional” CMS setup, in addition to non-run-of-the-mill e-Commerce, membership management, Contact Relation Management (CRM) capabilities, human resources, asset management, e-mail marketing, and/or complex access control. This niche is admittedly smaller than the previous one, which goes a long way to explain the smaller Drupal market share—not (and I realize I am a broken record here) because WordPress is “better” or Drupal “sucks” in some absolute sense.
2) Ease of development
WordPress sucker punches Drupal on theme simplicity. Seriously! When I develop a site in WordPress, I have never started from a pre-built theme. I start with beautiful, clean HTML/CSS markup and then add in WordPress theme API calls.
Drupal needs this simplicity in theming. With Drupal, I start from a base theme like Zen and bend the base theme to my design. This is fine, but on more than one occasion I have found myself spending too much time looking for a style class in the theme — if the code had all been mine to begin with, I would have been faster.
The learning curve for Drupal is steeper — I hear this a lot. I disagree! Every platform requires a developer to check the API documentation. I have used WordPress navigation countless times, but I still have to check the syntax of the specific api call from time to time. In Drupal, I do the same thing. The documentation for both platforms is rubust. If you know PHP I think they are the same.
