Plugin editor HTML TinyMCE vs CKEditor [closed]

I want to develop a plug-in for a HTML editor.

Which web-based HTML editor can I make a better and fast plug-in.

I´m not sure about:

TinyMCE
CKEditor

Which is better CKEditor or TinyMCE?

CKEditor is available under open-source and commercial licenses. TinyMCE is an online rich-text editor released as open-source software. TinyMCE is designed to integrate with JavaScript libraries, Vue. js, and AngularJS as well as content management systems such as Joomla!, and WordPress.

Is TinyMCE a WYSIWYG?

TinyMCE is a free WYSIWYG HTML editor. And it's one of those small, helpful components (consider how many websites rely on text entry) that you can't do without. It's the WYSIWYG editor of choice for the world's leading product teams.
