What are the benefits of presta over Schrader valves? (slrpnk.net)

My son recently got a really nice specialized bike used. It came with presta tubes on it, and a few extras. Last night he called me in the middle of the night to come pick him up because he had a flat and he could not get the pumps on campus to work with his tubes.

He said he could have probably ridden home on the low tire, but he was trying to fill it up but instead the pump kept releasing more and more air.

I personally see no benefit to presta valves, but there has to be some... right?

Presta valve cores are removable, so you can remove the core to put sealant in through the valve without unseating the tire bead, and can connect a pump to the valve stem without the core in to inflate quickly to seat tire beads on diffucult-to-seat tires/rims.

Schrader cores are also removable.

Everything here is true of schrader valves too.
