It depends on what you want to do with the car. If you want to go fast on a track, low weight is good and low end torque is not as important as horsepower.

If you want to haul heavy loads, a higher torque engine will move better as its usable power is in lower rpms.

Turbochargers allow you to reach higher horsepower output but require a higher rpm than a big normally aspirated engine.

And gearing in your transmission also matters. A lot of sports cars try to stay in the most usable power band of the torque curve so that is why they have more gears.
