I also work with different tools at work. Which one to choose? In my experience it doesn't really matter which one you use, just pick one to have your actions list and project list on.
If you feel like you are doing double work, moving projects from one system to another or moving actions from one list to a different, that doesn't matter. Even though doing double work isn't optimal, it actually pays off in the end anyway. Why? Because everytime you move something from one system to the other you renegotiate your commitment to the task/project and you can't help but to ask all these questions again and again "What is it?" "What does it mean?" "Is it actionable?". Continously processing and organizing will help you to get to done faster. GTD evolution in the making.
So start to do double work, then you are actually DOING something instead of just procrastinating. And you free up a lot of time since you don't have to think about the best tool.
