Why do some rushdown characters have long drive rush whereas some don't?

I'm asking this question to better understand my mains. Why do fireball-rushdown characters (i.e Juri, Dee Jay, AKI) have longer drive rush distances, whereas characters like Jamie or Cammy that need to get up close for damage, have much shorter ranges in comparison?

I just want to understand how these design changes are influenced or beneficial to their individual game plans.
