It depends on your engine/transmission combo + engine load. In my personal experience there's not much difference with my MTs. A shorter fuel intense burst in third or fourth gear uses about the same amount of fuel as a lengthier leisurely acceleration in fifth gear.
Lighter load/slower acceleration seems to work better with my family's ATs.
