Personally, I find that the DIVI theme and builder provides easier and more detailed control over the development of pages, blocks, etc. I've also worked with the Gutenberg editor (on many recent occasions) and still find it confusing (especially for users who need to do anything more than just change simple text, add a bulleted list, add some links, or add an image). I'll keep my eye on the Gutenberg editor as it moves forward. I just don't seem to feel it will ever become a solid replacement for the premium and independent website and page builders. But we'll have to wait and see.
