The models' case: Best overall indie value: MIT-licensed, lightweight, fast to iterate, excellent 2D, increasingly capable 3D, and no fees or vendor lock-in. The models' main caveat: Console releases require third-party ports or custom platform work. The strongest alternative is Unity — Near-tie for first when broad platform deployment matters.
