NIF's target cost millions of dollars to make. It produced 1.3MJ of energy, which is (generously) worth about a penny.
SPARC/ARC would enable a tokamak at a smaller scale (and self-sustaining from bootstrap current, most likely) but ITER is so far out of the running that something can be much better than it and still not be practical. ITER's gross fusion power density is 400x worse than a PWR's reactor vessel; ARC would only be 40x worse.
