A car and a vehicle is not the same thing, because a vehicle is not neccesarily a car.
The difference is Discreet (transistor, diode etc.) and Integrated Circuit (op amp, processor etc.) Both are solid-state devices. A well designed IC will always be better than discreet components because the silicon wafer/doping can be adjusted to a tighter operating tolerences. The only advantage to discreet components is that the designer has more freedom to modify his parameters to suit his liking. But, the discreet design always requires more passive components. The cost goes up. Another disadvantage is if one transistor goes bad, the replacement part may throw off the operating tolerences and cause distortion/noise and many opther problems. So, in discreet designs on super high cost pro stuff, the discreet components are hand selected to optimize the operating parameters of each individual circuit.
