You can't really compare Morgen vs Motion as they serve completely different needs. For example, Motion is a full fledged project management tool, you can use it either alone or with a team, it has an AI scheduler for your tasks and works literally like an assistant helping you plan and manage your day. Motion can be used for personal + professional use.
Morgen is simply a calendar that allows you to add basic tasks and reminders to your calendar. It's not as powerful and is recommended more so for individuals who want a better calendar experience than Google Calendar/Outlook and the ability to add basic tasks to the calendar. Morgen is more recommended for personal use.
