BusyCal vs 2Do
2Do is a dedicated task manager; BusyCal is a calendar-first app with tasks built in. Choose 2Do if lists, projects, and tags drive your day, and BusyCal if you plan by time blocks and want events and tasks in one window. You can also run both, since each syncs through shared services such as iCloud.
