In PowerApps they are called model-driven forms, and there is in-built version control! And although it's easy to write a HTML form, it tends to be slightly harder to write the code handling it on the backend to change the database, with full user/roll based authentication and validation - particularly if you are integrating it into your ERP. If the use case is a form to interact with Microsoft Dynamics, something built in PowerApps model-driven apps will be much more robust, quicker to develop and more secure than a html form with some custom handler.
