"Typically" sounds more like you have studied the question at hand. And people like to sound intelligent, so they like to use typically. But the two mean largely the same thing. Car drivers usually honk their horns at people in the street. (neutral) Car drivers typically honk their horns at people in the street. (I'm an expert on this subject because I just finished my doctorate and made a statistical study of car drivers honking their horns.) :-) (to be taken with a grain of salt)

There is almost no big difference between these words, so don't worry: use either one or mix it up, it doesn't matter at all.
