Bat versus Fritz X as anti-ship guided weapons

Was the US Bat guided bomb more capable than Fritz X against ships?

Yes overall: Bat's autonomous homing made it much safer and more flexible, while Fritz X retained an edge only in penetrating heavy armor.

Fritz X carries a strong armor-piercing advantage but requires the launching aircraft to remain exposed while an operator guides the weapon. Bat can be released and then guide itself to the target, freeing the aircraft to maneuver and reducing its exposure to anti-aircraft fire. That fire-and-forget quality is treated as the decisive improvement despite Bat's later arrival.
