Check out Chun-Li's Kikoken! How does it compare to Ryu's Hadoken? How about C. Viper’s Seismic Hammer? The interactions of the different fireballs was something we spent a lot of time balancing in Street Fighter Exceed.

While Ryu has superiority in Range and Speed, Chun-Li can block and counter a ranged attack with her Kikoken for an even trade. With a Critical, she’ll parry most of the damage from the faster fireball before throwing back her own.
