Many (some?) digital servos have extra features and can accept signal pulses at a higher frequency than analog servos but digital servos are backwards compatible with electronics for controlling analog servos.
A QuickStart board is a less expensive alternative to the PSC, if you're up to making your own adaptor to go between the QuickStart and the servos. By adding your own connections a QuickStart can control up to 32 servos (though you'd be out of I/O pins to used for sensors or communication if you used all 32 for servos).
The PSC would be a lot quicker to use than a QuickStart since the PSC has the needed servo connectors on the board.
