I suggest it depends on the runway? If there is a touchdown point marked then use that. If you are going into a relatively short field you want the maximum deceleration distance, so you use the numbers.
I suggest that for most pilots, they are much more likely to land long than short. If you are going to land short, get on the power. If you are going to land long / if you are fast and so will float, there is less you can do, but having aimed at the numbers initially will give you the best chance of getting it down first time.
I suspect though, it is the perfectionist in us - trying to be the most accurate, best pilots we can be, hitting precisely where we aim at (and there isn't another easily identified target at smaller airports).
