WGS-84 is more US-centric than is required by an international
specification, especially given the expectation of the Galileo
Terrestrial Reference Frame GTRF
http://www.ggsp.eu/ggsp_gtrf.html

At the level of 1 m any of them will do.

Below the level of 1 m WGS-84 has changed and as of today does not
produce the same results as it did a decade ago.  This is geodetically
akin to the leap second -- the reference point changed -- except that
in the case of GEO the current language makes it clear that nobody cares.
