Bike News published an explainer on the structural difference between "opposed-piston" and "pin-slide" hydraulic disc brake calipers. Opposed calipers fix pistons on both sides of the rotor, while pin-slide calipers use a single piston with a sliding mount so both pads clamp evenly, and the piece notes that braking power differences mainly come down to rotor diameter and pad area rather than caliper type.
