My opinion is opposite. Its easier to pump upwards.
Usually you can lift more weight that you weight by yourself... when tightening vise for example, lifting is easier.
Same with the jack, you can use your feets for pumping, when pulling down you can only use your hands or your weight..

So, there's no actually "best" solution for that, i like that lifting handle up works better than pressing it down.
