The short version
Stay with Google Tasks if a simple list inside Gmail and Calendar is enough. Pick Palby Planner if the list has outgrown that: you want projects, labels and priorities, a timetable for the day, and routines and habits beside it.
Who should pick which
Stay with Google Tasks if
- You want tasks right inside Gmail, Calendar, Chat and Docs
- A few lists with starred tasks are enough
- You work in Google Workspace and assign tasks in shared docs
Pick Palby Planner if
- Your list has grown past a few lists
- You want to see the day on a timetable, beside your Google events
- You want habits, routines and notes in the same place
