As of the selected ranking year, Barbra Streisand and Diane Keaton form a comparison shaped more by career pattern than by any single credit. The category score gives Diane Keaton the broader edge, though the result remains a comparison of career outcomes rather than personal popularity.

The biggest-hit category sharpens the box office contrast, especially because Diane Keaton's leading film creates the stronger single-release benchmark. Overall, the head-to-head score leans leans toward Diane Keaton, but the strongest context comes from the categories where the gap is clearest.
