Which visual editor to choose for drafting contract documents?

Question

Documentation

We all know how various contracts look visually - heading, text, all kinds of paragraphs, tables, at the bottom there is a place for the date and signature. I was given the task of choosing a visual html editor for this case, so that such documents could be compiled directly in the browser.
Now I'm choosing between CKEditor, TinyMCE, Summernote and some others. Who faced tasks close in terms of setting - tell me please, what to choose? The editor must be both very powerful and easy to use, as it will be used by people who are far from programming and development in general)
