Does GVC even improve the handling in Mazdas? As far as I know it only improves the ride comfort and doesn't contribute to any improvement in handling. It's like ESC which doesn't improve handling.GVC, no. GVC+ perhaps.
GVC+ adds braking on the front wheels so when you turn into a corner, braking is applied onto the inside wheels and then it applies braking to the outer wheels when the car senses the steering is returning to the center.
this makes the car drives a little bit more direct/sharp, pointing the nose of the car more accurately in the direction which corresponds to the steering input. the effects of GVC+ can be felt/seen when driving in a round-about and you need not make small adjustments to the steering and the car will just cruise along around it.
to truly say that a car handles well, it depends on many parts/components (eg: suspension, chassis etc).
one of the main difference between ESC and GVC+ is that ESC kicks in only when the car senses a loss of traction on the tires (usually in an emergency) whereas GVC+ is constantly working in the background and doesn't only work when there's a loss of traction on the tires.
