Well, Coquand-Sattler might be better because it was first used in the
[CCHM] paper. From the many anodyne monos of the test model structure
one took just those which were syntactically convenient.
But, as far as I know the test model structure also gives rise to a
model of cubical TT because its more restrictive class off fibrations
suffices for interpreting sytax.
