Obligatory rude question: If you're a professional website designer, why are you asking us? Don't you already have a preference?
Plenty of professionals use big-name CMS (WP, Drupal, Joomla). Plenty of others roll their own. Pros and cons each way. It's the designer's decision: Options a, b and c are client's choice; options d and e are non-negotiable.
I am not rude. As i want to know what other do i asked this question. I wanted to check whether i have been travelling in the right path. I wonder how it seemed to you as rude one. Pls avoid this kind of rude replies.
