The editor I require, needs to be easy to use. Even for people with absolutely no HTML knowledge
The projects I have tried are:
I had to build a CMS from scratch a few years ago. Went through so many options, tore TinyMCE to pieces, also tried CKEditor, etc etc. I really liked summernote and ended up using that. Seemed like the most drama-free option at the time and worked flawlessly.

Come to think of it I might use it in my next project.
