Having trained on the TH-57A (its last training sortie as a student graduate Naval Aviator), B and C models, I would define the 57 as venerable, not just ageing.
Looking at the contestants, I do believe the 119 is the best platform for the job, however I understand that the RFP is not to be limited to the airframes themselves but rather to a "turnkey" training package including simulators at a minimum.
It will all be decided in DC.
Let's see which contestant can carry the biggest suitcase.
