It's about making the right choice.

If you create content, Umbraco CMS is easy to use via the simple and logical interface. It is therefore intuitive to find your way around and reach the desired result. You can e.g. use a media library to easily manage images, PDFs, etc. And then you can plan your content so that you get an automatic publication when it suits you. It is efficient and less resource intensive.
For you who develop and design, it is essential that there are integrations to other business systems, that are APIs that are easy to use via a developer access, and there is a design freedom that does not limit you in your dreams.
