I had a Schrader tube on my wife's bike completely fail once when the entire valve stem pulled out of the tube as I was trying to remove the pump head. In general I find that removing the pump head to be more difficult on Schrader valves than on my Prestas.

I don't use the Presta caps that come in the package as those are meant only for packaging to prevent the valve from puncturing the tube in transit. So for me it's easier to just unscrew the Presta valve than it is to unscrew a Schrader valve cap and then have to put it down somewhere or hold it while pumping the tire. I do not like to leave Schrader valves uncapped (on both cars and bikes). I also prefer threaded Presta valves with the retaining nut since it keeps the valve from pushing back into the tire when I'm trying to attach the pump head. Putting the pump head on an empty Schrader tube/tire/rim can be pretty difficult sometimes.
