This primarily comes up as the pressures in the tires get higher.
With lower pressure wider tires, Schrader makes the most sense, if only because you can hit a gas station for some air pressure.
Presta makes more sense on higher pressure tires, since it allows you to pump in higher levels with a floor pump. Per the comments let me try and clarify. When you use a Schrader stem the valve is depressed by a thingy in the pump head the whole time. With a mechanical constant pressure pump (like at a gas station) this is fine.
But with a floor pump where there is a pause between pumps, Presta works better because each time you release pressure, the valve head closes. Then as you build pressure in the pump, when it exceeds the tires current pressure it forces the value to open, allows air in, and repeat. Thus you can pump to higher pressures with it. (Or at least with poorer quality pumps.
But if it bothers you, get the little one dollar adapters, and you can use a car pump with no issue.
