One of the things I love about WordPress is that the project has a clearly-stated philosophy. One of the principles is to design for 80% of users and leave plugins to fill in the more advanced features.
This is happening with the Gutenberg block editor. Many developers are adding extra features on top of the default blocks.
Inside the PublishPress Blocks plugin, the Advanced List block is based on the default List block in Gutenberg.
The Gutenberg team have done the hard work. We're standing on their shoulders.
If you want to show lists in WordPress, both the List block and the Advanced List block are a great choice.
The Advanced List Block has functionality that the extra 20% of WordPress users may find helpful. If you are a WordPress power user, you'll want to check out these features, especially the custom icons for list items.
