Turboprop VS Turbofans

The ATR ( Avions De Transport Regional ) is Celebrating it's the 39th Anniversary. Of late, they have pioneered the Turboprop regional jet industry.
On this occasion, It's compelling to highlight the Beauty of these turboprops.
Turboprop propeller have a large diameter compared to Turbofans, it accelerates a large volume of air, the Bypass Ratio can be 50 to 100.
As it accelerates a large amount of air by a small degree, a low disc loading increases the aircraft's energy efficiency, very fuel-efficient.
Modern turboprops operate at nearly the same speed as small regional jet airliners but burn two-thirds of the fuel per passenger, very miser.
When Compared to turbofans, turboprops are optimum at flight speeds below 725 km/h and FL250 Altitude because the jet velocity of the propeller is relatively low.
Turboprops have lower landing speeds and hence can land on short runways. Some airplanes such as Twin Otters can land on runways which are less than 1,000ft in length.
Turboprops are suited to unpaved runways as well. Dust and FOD objects have a significantly less impact compared to turbojet engines.
Turboprops have lower acquisition & operating costs. Lifecycle operation costs of are lower as compared to turbojet aircraft (segments).
