Yes, a prop will typically burn less fuel/mile, but it's nowhere near half.
Was a simple statement yes, but I am rated on AE2100 and AE3700 powerplants. Cores are very similar. One has a propeller off the LP shaft, the other a Fan. Taking the types, both carry similar pax loads and weights. Yes one can fly 50 knts faster if it wants to and a bit higher. The jet burns a considerable higher amount of fuel that the turboprop on the same 400/500 mile sector and the prop was not much slower. Costs do add up. My last company base had turboprops. Swapped for jets, fuel costs made the base unprofitable, base closed.
