You right, diesel is the best solution for daily driving.
1. Fuel consumption is lower.
2. Higher torque than petrol engine.
But the drawbacks: if diesel fuel has bad quality, the modern engine will literally die (thats why supply for modern diesel vehicles is low in countries like Ukraine or Russia). The second drawback is narrow rev region for power output, which is not bad for daily driving, but bad for performance driving
