r/drupal: Why not WordPress
When my clients ask "Why not WordPress":
Not only is there often a separate licensing cost associated with WordPress plugins, coding standards are lacking or non-existent in the WordPress plugin marketplace. This often leads to disproportionately and unexpected costly WP developer support, and frequent release delays, increasing overall security risks.
Not to say these things don't happen with Drupal and contrib modules, just less frequently.
Through my direct involvement of various Dev Shops over the past 20 years, has revealed another factor, which is often overlooked: Drupal sparks more joy than WordPress. As a Technical Manager, my currency is in passion and velocity and when my team members are frustrated by the work, risks, delays and costs rise, often snowballing towards the end.
