Pomodoro technique is just a tool to force you to concentrate in your work. Personally I use both pomodoro and org-mode. Sometimes it works for me sometimes its not.

I would like to suggest another tool or option for you to try though this is not about pomodoro technique but if you wanted to be productive, you might want to read this book:

The Power of Concentration
