My employer had an argument with me as he didn't like the fact I was starting from a stop in 4th gear. He said it is better to shift into 1st gear when starting from a stop. While I said it is better to start in 4th gear, giving it lots of gas and engaging the starting motor, and allowing the clutch to slip, only raising it once you are within the gear's speed range. I argued that this was better for the car in the long run as you don't always have to shift gears, saving stress and wear on both your clutch and syncros. It also makes driving a manual in stop-start/heavy traffic alot easier.
Who's method is right in terms of overall car health?
