How should you make the decision?
Start with the work your company needs performed, the decisions that require internal ownership, the amount of day-to-day capacity required, and the risks of changing models. Then ask providers to map their scope against that operating picture.
A model is not a quality guarantee. Service teams, implementation, systems, pricing, and contract terms differ materially within every category.
