They're a little slower, use a whole lot less power (saves pennies per
hour), meaning less heat (pennies per hour saved on cooling), less
vibrations (increased lifetime, less need to noise-isolate disk setups
to avoid vibrations slowing seeks).

Unless you _NEED_ the 125mbytes/sec-per-device transfers of the 7200rpm
drives (you can live with 100mbytes/sec), then go for the 5900rpm drives.
