I most definitely favour the Novus Ordo as an excellent reform of the Roman liturgy, Trindentine and earlier. In my opinion, the vast majority of the Novus Ordo changes are fully justified as required restorations on the INTERNAL EVIDENCE of the theological purpose of Christian public worship. For instance, from the very beginning in synagogue worship right on through the Tridentine liturgy, especially in it full Missa Solemnis form,  it is obvious that the purpose of the Liturgy of the Word is for the Word to be proclaimed and responded to and explained to the holy people of God. On that internal principle alone, the shape of the Liturgy of the Word has been restored to a form that the apostles would recognize, and Christians from the 4th century onward would have found self-evidently meaningful.

As for the Byzantine Diving Liturgy, I accept the view of Dom Gregory Dix in "Shape of the Liturgy."  It's development did not begin to go off the rails until the 8th (Roman, after the 5th).
