 - It offers a substantive API on top of the DOM. Most of CKEditor and TinyMCE's APIs offer little more than syntactic sugar on top of existing DOM APIs. Quill maintains an internal document model and does not rely on the DOM as the source of truth, allowing it to offer far more powerful and relevant APIs for text editing.

-- Draft's API inherits primitives and ideas from React, that is more appropriate for general websites. Quill's only use case is rich text content so its API can be much simpler and specific towards this use case. API simplicity and design is subjective so the best metric for you might be to think of a common task, like bolding a range of text, and try to figure out how to do it in Quill and how to do it in Draft.

 The main difference is still that Quill is a ready to use rich text editor, with user interactions considered and interfaces thought out and implemented. Draft provides the building blocks but you will have to implement all the pieces above the data layer yourself.

-- Both Quill and ProseMirror implement and maintain a data model to operate on with APIs, instead of allowing users to modify DOM directly.
