>With most commercial aircrafts using turbofan engines which makes it faster.

Because speed isn’t the only thing to optimize for.

Turboprops are considerably more efficient at slow speeds and lower altitudes. This also makes them capable of taking off from shorter runways.

Also it’s considerably safer to take off from a dirt runway with a turboprop than a turbofan because you don’t have to worry as much about the engine ingesting rocks or whatever.
