Depends.

If you need an accurate time on an RPi and it doesn't have a permanent,
reliable connection to the internet but does have enough power to run a
GPS receiver then using a GPS may well be the best choice. Or you could
use one of the very low frequency time signals, e.g. MSF ('Rugby') or VVV,
plug in a suitable receiver. If you use MSF then receivers are available
from Galleon.

Equally, if you have a spare GPS receiver and want to experiment, using
that becomes a nice, cheap solution.

OTOH, if there's a reasonably reliable internet connection where the Pi
will be installed, use the NTP time service.
