What are the differences between V brakes and disc brakes, and which one is more suitable for my bike?

V brakes are traditional rim brakes that use pads to grip the wheel rims for stopping, while disc brakes use a rotor and caliper system for braking. Disc brakes generally offer better stopping power and performance in wet conditions compared to V brakes. Disc brakes are more suitable for mountain bikes or bikes used in wet or muddy conditions, while V brakes are sufficient for casual riding on paved roads.
