I've been through them all and find that no one solutions is complete. I follow the basic principals of GTD focusing on safe places to collect tasks (inboxes), regular review of all inboxes to organize inputs. Important note: If you can do it in 2 minutes do so. If it has more than one step, spend time writing the all the steps you can think of to get a clear idea of what you need to do. InBoxes: OneNote for easy input from every tech. Field Notes for hand writing which can't be beat. OneDrive for anything files I need to review. Blank paper at my desk while I work. Then, for project execution, I follow more of a Cal Newport approach of Time Box Planning and unplugging to perform deep work. Hope this helps.
