Both of the rejected formulas are crypto-modalist, IMO.
"Father", "Son", and "Holy Spirit" are personal names, or at least identifiers of a relationship ... thus implying distinct persons.
Creator, Redeemer, Sanctifier, Liberator, and Sustainer are all job descriptions. That's modalism right there, whether intended or not.
The folks who use such "doxologies" are heretics.

Nothing “crypto” about them! Modalism pure and simple.
