Actually, a turboprop engine has more, not fewer, parts than a jet engine.

The ride of a turboprop is different but it is not because of the size of the airplane, it is because of the airplane's wing loading. Wing loading is the total weight of the aircraft divided by the wing area. Wing loading will be higher for airplanes that are designed to cruise at higher speeds and lower for those designed to cruise at lower speeds. A lower wing loading also produces slower takeoff and approach speeds which allows the airplane to operate on shorter runways.

A jet often has a smoother ride because it can climb out of low-level turbulence but low-level turbulence is not universal. Many days have smooth conditions at lower altitudes so all airplanes will get a smooth ride. Other days will have high altitude turbulence which the jets must endure as their higher low-level fuel burns won't allow them to stay below.

Going into CHO, the low-level turbulence will most often be associated with windy days.
