On the A320 you need to remember to move the levers back so that commanded thrust is equal to current thrust before disconnecting A/T or power goes straight up to climb setting.
Being able to pull the levers back on a Boeing without looking at the instruments first, getting advanced warning of a commanded power increase and being able to prevent it simply by holding the T/Ls back would be something pilots transitioning onto Airbus would miss.
Experienced A320 pilots on approach can control thrust using the side stick, anticipating sink and applying back pressure will give a thrust increase, anticipating ballooning and applying forward pressure gives a decrease. Inexperienced pilots often have difficulty and get "out of synch" with the aircraft resulting in porpoising around the glide path with ever increasing thrust changes.
