Volt still has a faster speed boost, and Speed works on allies once cast, unlike Jet Stream where your team has to be within the radius for them to get the benefits.

Speed also gives a melee attack speed boost, while Jet Stream gives a weapon projectile speed boost, so they still have different functions.
