It has UTF8 support and is translated into many languages.

Taskworrior allows you to define custom attributes and reports to your needs.

You can be in full control of your data.

Omnifocus allows users to setup the "defer date" which can be treated as "start date". Tasks will not be marked as available until that date, which should help to focus on the "available" task only.

The forecast summary shows a quick digest of the tasks you have for the day. You can select any day to quickly see what tasks you have planned that day. For extra functionality you can connect with the iPhone’s Calender app, which allows you to also see any other events you have planned that day.

The Perspective section allows you to see an overview of the tasks you have set. It also allows you to set contexts or see things you have flagged.

OmniFocus 2 allows you to set up contexts for tasks in certain areas. This makes sure you never miss a task when you're out running errands and happen to be near something you need to do.
