A comparison of the GTD / Todo Apps for Android

What I look for in a GTD App:
- alarms/notifications that can be set per hour/daily/weekly/monthly & yearly
-sync with online services like Toodledo.com,Google Tasks, Google Calendar, Dropbox, Remember the Milk, etc.
-prioritization
-ease of adding tasks
-ease of viewing tasks
-projects and subtasks capability
-notification by location
-interface
-sorting
-searching
