Notion vs Walling
Notion is definitely a more versatile tool. You can configure Notion to handle sophisticated workflows that could power the work of your whole company, and provide automations in places where it makes sense.
Walling is less versatile. Instead, it tries to improve productivity by arranging information in a more visual manner and making things work out of the box without the need to configure much.
