What are the differences between bicycle disc brakes and rim brakes, and which one is more suitable for my riding needs?

Bicycle disc brakes use a rotor and caliper system to stop the bike, while rim brakes use pads that grip the wheel rim. Disc brakes offer better stopping power and perform well in wet conditions, but are heavier and more expensive. Rim brakes are lighter and cheaper, but can wear down rims and are less effective in wet conditions. The choice depends on your riding style and conditions - disc brakes are better for off-road and wet weather riding, while rim brakes are suitable for casual riding on dry roads.
