You are technically right, but if you were asked if you would prefer a 1 kg brick or a feather bag of the same weight to fall on your head, what would you choose

As for the merits, the bigger battery is better than the smaller one, if only because the bigger battery will last longer in a car that has not been fired for weeks. There are other reasons, which have already been extensively discussed - and the most important reason is the starting current, especially in winter, especially in diesel, especially in a few years old battery.
