Exactly: I am usually writing backends for financial systems which need high throughput and low latency; dynamic is just a massive performance hit. And almost never needed; people usually use it because lazy in my experience. It is just ‘faster’ for people to dump JSON into dynamic and write against that than it is to properly create structured classes. In the end ofcourse the unittests validate the JSON, the code is slow and harder to use and refactor; you would have saved time and stress actually just writing classes with proper typing.
