MARS vs Drupal
Drupal's strength
Drupal offers configurable entity types, taxonomy and multilingual content. It is a serious option for content rich teams that want its established ecosystem and configuration model.
How MARS is shaped
MARS uses Laravel modules with owning application services, a React Admin and presentation only themes. Its content routing and business domains are designed to work together inside one installation.
Choosing between them
Choose Drupal when its entity and module ecosystem fits your team and project. Consider MARS when the website is also a business application and you want its specific integrated workflows and update model. Evaluate implementation capacity, not a scorecard.
