Why I was even thinking about it at all was that one of the models I
looked at said the 10KHz was more accurate than the 1PPS, so I was kind
of thinking about that. If the Ubloxes have 1PPS which are just as good
then there is no reason to think about a 10KHz.

You are correct. But this guy is building a nixie tube clock. The
clock should increment the seconds at the tick of the UTC second.
There really is no way to do this without using the PPS. The serial
data is not aligned with the UTC "tick"
GPS receivers work just like the old telephone time service "At the
tone the time will be..." and then comes the leading edge of the 1PPS.
If he were building a frequency standard then, yes the 10KHz signal
would be the best one to use.
