Some people say to build React as front-end it is neccesary to use wordpress as headless CRM, but I wonder what is the difference between such a solution and using gutenberg to create subpage templates? This solution seems simpler because I don't have to use REST API or GraphQL to transfer data, I also save on hosting. I'm just curious about the difference in quality.
