Pros
Pro Defer date
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.
Pro Forecast summary
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.
Pro See an overview of all tasks via "Perspective"
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.
Pro Nearby and context-sensitive tasks
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.
Pro 100% Free
Just like todo.txt cli, this is 100% free (although donations are accepted).
Pro Also comes in a cloudless an Owncloud version
For those who don't care about syncing there is a cloudless version while people who run Owncloud may opt for the Owncloud version.
Pro There is an add to calendar button
This not only tells one's calendar (and thus any devices that sync with your calendar) about the todo, but allows all synced calendars to play an audible alarm when the todo is scheduled to be finished.
Pro Seemless compatibility with todo.txt cli
Let's one sort to-dos by due date then priority
