I guess it would depend on the player is more likely to use it for. Railgun probably has the best gank due to the range and missile speed increase - whereas Chain Lightning would be more of an in-fight mobility/AOE damage tool. He can keep himself out of harm while dashing from pylon to pylon dealing damage.
