Question on which is best bridge to cross SF Bay

I go to Stanford ab out once a month. I take 80 to 880 to the Dumbarton. I also take 24 through the tunnel and then S. on 13 to 580 to 238 to 880 to the Dumbarton, depending on how much traffic is on 80.
Now, if you are coming down 80, you can take 680 to Milpitas and take the 237 across to 101 and jog North to Palo Alto. That way you will avoid a $20 bridge toll on any of the bridges.
