I made a good faith effort to use the new editor, and honestly expected to like it. Unfortunately, I did not, and have since installed the Classic Editor plugin. A few specifics.

1. The new editor is not a good fit for the model of my main site, which relies on content written externally, converted to html, and pasted into WordPress.

2. I'd like to keep playing with the new editor on some sites, but the Classic Editor plugin is network-wide, so I can't use Classic on some sites in a network, and the new editor on others. That's a mistake, since I can see the new editor working fine for some (more layout-specific) cases, but not for the main site.

3. Some decisions are decidedly counter-intuitive - like the decision to put the Publicize feature behind the Publish button. Publish no longer publishes the post, but gives access to a backstage area from which you can then publish. Who thought this was a good idea?

I think the suggestion of above of not making each paragraph its own block is a good one. That would make the new editor a much better fit to my use case, at least, since generally I'm publishing big blocks of externally-generated text with just one picture. The new editor only seems to fit the case where all content is prepared in WordPress. I can't be the only one who doesn't work that way.
