Some thoughts on Joomla vs. Drupal...
The content management system (CMS) really depends on what you are using your website for. Joomla is good for community sites, while Drupal is better for professional business sites where multiple employees are editing and adding content.
A third party live chat can be integrated into any website, with or without a CMS. And ticket system would work in both Joomla and Drupal, as well as online forms and slide shows.
It really depends if you are thinking about expanding your site into a community site or leaning more toward a corporate website. For corporate websites, I would normally use Drupal for a more basic look and functionality.
The speed can be optimized for any CMS, even hand-coded sites. Both Drupal and Joomla offer tools for this, as well as tools for search engine optimization (SEO).
