The List Block and the Advanced List Block
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.
Here's a side-by-side rundown showing the extra features in the Advanced List block. The features on the left are enough for 80% of users. The power features for 20% of users are on the right.
Custom Icons
List Block
The default List block has 2 options allowing you to use either unordered or ordered lists.

Advanced List Block
The Advanced List block allows you to choose from over 20 different icons for your unordered lists.

Each icon provides a choice of size, height, margin, an padding.

Summary
The Gutenberg development team have done an excellent job with the default blocks. On multiple occasions, our developers have been able to build on top of their work and add 20% more. Some examples include the Advanced Button block, the Advanced Table block, and the Advanced Video block.
