The main difference is that with props you don't need to think to plan your descent, you can descent on a constant 3 degrees glide all the way to touchdown, or you can dive if you need, or you can slow down on the glide simply by advancing the condition levers forward.
It's like driving a car with brakes.
On jets, you need to plan your descent, allowing for a level segment before intercepting the glide, or smilar...
It takes some thinking and experience to do it right, especially when they are keeping you high... you must find the most elegant way to loose altitude.
Drop the rubber brakes? Shake the airplane with speedbrakes? Extending flaps fully? Exactly when?
Jets burn a lot at low altitudes, and you don't want to increase too much your drag and then having to increase power for a level segment at 3000 ft for 10 miles....
It's like driving a car without brakes, you must think ahead to use your engine to slow down before a turn.
