Compare Productivity Systems for Your Work Style

You have tried a system because everyone raved about it, then quietly abandoned it three weeks later. This compares systems on the mental overhead each demands, how flexible they are, whether they suit your kind of work, and how likely you are to stick with them. You pick one that fits your brain rather than someone else's productivity blog.

You are trying to find a productivity system that actually fits how you work, rather than adopting one because it is popular. You want to compare {SYSTEM_A} against [one or two other systems] with honest criteria.

**Compare the systems across five dimensions:**
1. Cognitive load: how much mental overhead does maintaining each system require day to day?
2. Flexibility: how well does each system adapt when your work is unpredictable or project-based rather than routine?
3. Capture and processing: how each system handles the flow of incoming tasks, ideas, and commitments
4. Review cadence: what each system requires in terms of weekly or daily review, and whether that is sustainable for you
5. Proven fit: the type of work and personality each system tends to suit best, based on practitioner experience
