3-3>3-4
Hill>Smith
Plus, the three games that the Whiners won that Smith started (CHI, JAX, AZ) they would have won those games under Hill also. They won those games because of defense, not anything Smith did.
If Hill had started against Indy and Seattle, maybe they win those games. Even one TD drive in the second half of those games probably would have led to a SF win, but Smith didn't do squat in the second half of either game.
Of course Ronin and Singletary would go out of their way to make excuses for Smith and blame Gore, the WR's, Davis etc., but the fact is that Smith didn't get it done and hasn't over his career.
If Hill had been the starter all season, SF is probably 7-6 or 8-5 right now. I hope SF signs Smith to a looong extension this offseason.
