Classic debate of range vs damage i suppose, the ballistics and capability to throw the can of soup would increase it’s effective range, but you’d have to rely on accurate shot placement to do considerable damage, like the head, ribs or abdomen, which is entirely possible with enough skill considering the can is much easier to throw and to apply a little bit of rotation into it, which would result in conserving it’s energy thus extending it’s range and accuracy, a can of soup is a fine choice for a true marksman with high fidelity in dexterity and quick calculations. The brick on the other hand is the true brute’s weapon, a man of strength and brutality, channelling forth your ancestors into an uncalculated, feral lob would result in devastating damage no matter where the hit takes place, however, it is a much less aerodynamic and a rather awkward shape, resulting in less than favourable accuracy and range, most lack the ability to effectively launch such an object, but fear and dread the wretched creature that can, a beast that only cares for violence and indiscriminate destruction, there is no reasoning with such an animal, the can thrower may have range, intellect and accuracy, but the brick thrower has the intent to harm, a willingness to do whatever it takes to make ends meet, the savage brawn of the brick thrower may be tamed by the can thrower if kept at bay, but lord rest the soul of the brick throwers opposition if he gets within range to strike.
