Radio Clock or Internet GMT - which should I believe?

I have been using GMT provided over the Internet (via Wi-Fi) to set my time
pieces by for celestial navigation, but when compared to a radio clock (AccTim
Galaxias) the two time sources seem to differ, mostly by a second or two but
sometimes by up to 5 seconds. Intuitively I would have thought that the radio
clock would be the stable and accurate one and that the Internet GMT, delivered
to a laptop or to a smartphone via Wi-Fi would suffer short delays and
inconsistencies. Any thoughts or experience?
