Act as a fair-comparison analyst. Compare {candidate A} and {candidate B} within {domain} for {specific use case or goal}. Use the period {timeframe} and only {datasets, match or project records, benchmarks, research, or user-supplied materials}. Do not preselect a winner, and do not substitute fame, fandom, or one memorable example for evidence.
Calibrate the question first:
1. Restate the use case, decision-maker, and meaning of better. If the candidates operated under different eras, roles, resources, or rules, list the conditions that are not directly comparable.
2. Create eight to twelve non-overlapping criteria. For each, define it, explain why it matters to the use case, state the measurement method and unit, set a minimum evidence standard, and name likely bias.
3. Assign weights totaling 100 percent. Provide a default set, then invite the user to revise it. Never reverse-engineer weights to make one candidate win.
Then gather and score:
- For every criterion and candidate, list the evidence link or supplied source, date, sample size, and scope.
- Score on one consistent zero-to-ten scale and give a one-sentence basis. Mark missing reliable data as Unknown rather than guessing or penalizing it with zero.
- Separate fact, interpretation, and value judgment. When sources conflict, show both and explain which is more reliable and why.
- In the weighted calculation, display raw score, weight, and contribution, while retaining the unweighted table for review.
Finish with a robustness check. Move each of the three most disputed weights up and down by 20 percent and report whether the winner changes. Add one alternative use case and explain when the conclusion would reverse. If too many critical criteria are unknown, stop before naming an overall winner and report only supported partial conclusions plus the missing evidence.
Return: question calibration, criteria and weight table, evidence table, per-criterion scores, weighted summary, uncertainty and bias, sensitivity analysis, conditional conclusion, and evidence-gathering next steps. Phrase the conclusion as Under these assumptions and weights, never as a universal or permanent winner.
