This is not obvious from the link but I guess this is posted because of v2 released 3 days ago.
I have been working with Quill v1 not long ago and oh boy it is not good. Pain to make tables work with plugins and weird scrolling issues. Hopefully v2 fixes a lot but I'm sticking with TinyMCE as it is superior in term of features.
I like TinyMCE too and swapped out a Quill editor in its favor 6 months ago. But I was annoyed that you needed an API key to use their static JS in your site and disturbed that they rapidly shrunk free tier "use" of rendering an editor a few days back [0]. Out of curiosity, is that not an issue for you?
