I remember the jetstream 31 was a handful at low speed when the rpm was changed due to the different response time of the left and right engines. Quite a lot of aileron input would be needed during changes of thrust. I guess if all your practice go rounds are single engine, then you know which way it will roll, but a 2 engine go round would produce a roll that may not be predictable.
Different aircraft had different characteristics depending on how well they had been set up by the engineers.
