In my experience, most of the people on the #62 bus are airport and airline employees. I've never seen anyone scary on that bus. And buses are inherently safer than subways anyway, because the driver is right there and escape is possible (to the street).
To get to 33rd Street on PATH, you have to change trains in Journal Square, which is time-consuming in itself, then the second train makes too many stops. It does go to 33rd Street, technically, but I always get off at theback of the train, which is at 30th. Not a big difference (780 feet!).
I guess everyone is entitled to his own opinion!
