I dislike Gutenberg - I've tried it multiple times and found it too confusing and highly restrictive.

I just use classic editor to design sites for my clients, 99% of whom never update the pages (I do it for them) and they simply use the CMS to write blog posts or sell via woo. The WYSIWYG editor is perfectly fine for those tasks.

Guttenberg is an unnecessary complexity that's simply not needed.
