I think there could be a decent dose of "backup contract" in the mix
as well. ATC and ATD were contracted very close to each other,
timewise, along with Westinghouse GP-7s.

The Collins Autotune was a new technology for the Navy. They had a few
shore transmitters that used them just before the ATC came into being.
With no long term experience, I would bet the Navy did not want to
sink everyting into the fancy, expensive, unproven megamechanical
design.

This was probably a good idea. What if the Autotunes failed? The Navy
would be in a jam if they had no backup.
