In reply to Bastian.

Most of the theme developers I talk to say that it is far easier now to have the site look the same on both the back and front end. That has been my experience as well. I still shudder when thinking about styling the old visual editor and the headaches it gave me. The block editor still has a few problematic styles that you must overwrite, which can sometimes change between versions. Other than that, it's nearly one-to-one to style them today.

If interested, I can put you in touch with a private chat group that has several top theme/site developers who have been building block-styled themes for at least two years. Feel free to shoot me an email.

The biggest complaint I see is the changes between versions, and I have been vocally critical about this issue in past articles. Part of that is building something too fast without thinking enough about third-party development in the long term.

For a lot of CPTs, I wouldn't recommend the block editor right now (it can be disabled when registering), particularly if they are more focused on meta than post content. It really just depends on the situation. CPTs are custom things, so the solutions are going to vary.

Anyway, thanks for chiming in. That is useful feedback that I hope the dev team reads.
