Agree. It's not all about the content.

In terms of data entry on a custom post types with custom fields, if you are using custom field groups set up in metaboxes, as is the case with Toolset, the user experience is much better:

• There is a better clarity in terms of the form to be filled in, contrast between elements in the UI is better

• Metaboxes/field groups can be arranged to match any use case, and this holds true for the standard post controls as well such as featured image and Categories etc.

Outside of content you may also be working things like Yoast. On a given day you or somebody else may want to work across all posts for SEO purposes. To save having to scroll down under the metaboxes you would drag Yoast to the top to speed up the worklow. NOTE: You can only position something like Yoast directly below the post title if you have configured your CPT to exclude the content text area or if you have activated something like the Divi builder.

Yes, Gutenberg may look prettier but it is not as functional as the current editor. Yes, the current editor looks like the cockpit of an Airbus to novice users, but to many there is an expectation of this level of complexity in a professional tool such as WordPress.

The developers at WordPress have a lot of work to bring the same level and functionality and flexibility to Gutenberg.
