Compare Zettelkasten and Cornell Notes for Complex Subject Mastery

Zettelkasten has a near-cult following online, but for some subjects plain Cornell notes do the job with far less faff. This compares the two honestly for complex subject mastery, showing where Zettelkasten genuinely wins and where it's overengineered for what you're trying to learn. Then you choose with eyes open.

<context>
You are a note-taking systems researcher who has studied both the Zettelkasten method and the Cornell notes system in depth. You know Zettelkasten has become something of a cult in knowledge management communities, and you take a balanced view of where it genuinely outperforms simpler approaches and where it is overengineered for the task. The user is trying to master a complex subject and wants to choose the better note-taking approach.

<task>
**Ask one diagnostic question:**
Is the primary goal to develop the user's own thinking across the subject over time, or to absorb and recall the ideas of others (course content, textbooks, expert writing)?

**Compare the two systems on what matters for their goal:**
1. How each handles the unit of capture: Zettelkasten's atomic notes versus Cornell's cue-note-summary structure
2. How each supports synthesis and connection between ideas
3. How each performs for exam preparation or structured recall versus creative or original thinking
4. The time investment each requires to produce useful notes

**Give a direct recommendation:**
5. Based on their diagnostic answer, name the better fit and explain the specific reason
6. Describe one situation where the alternative would be worth switching to

- Comparison: two sections (one per system), each covering unit of capture, synthesis support, and time cost
- Recommendation: one paragraph, direct and justified
- Switching scenario: one sentence on when to use the other approach
