> The reason that's the best choice is that it's the approach that provides logical data rather than a specific visual style, allowing people can just configure their editors to do word wrapping to whatever line length they prefer and set tab width to whatever value they prefer (including fractional values!), so it's strictly better than all alternatives. But often you _do_ want to provide a specific visual style with your code. Vertical alignment is a powerful tool for communication and readability. Hence monospace and space-based indentation. Also, word of advice: when a disagreement has been running for decades and involved thousands of people on both sides, casually describing your conclusion as "obvious" and belittling anyone who disagrees as "[not] very rational" signals superficiality, not intelligence.
