Both Things and Todoist are excellent apps. But if you are immersed in Apple products, Things offers more linkages with other Mac apps, such as drag-and-drop Mac Mail conversion and Applescript automation to add powerful new MYN features. Things also offers drag-and-drop task prioritizing in its MYN configuration--no other app has that. And it has both start date and deadline fields. In contrast, while Todoist lacks all that, Todoist has more extensive project management features, and both Toodledo and Todoist are multi-platform so they also runs on Windows.
