Both right, just talking about different things. What most people don't account for is the time shifting. To make that apparent, you can drag-race two identical bikes and you'll see that lower-geared bike may take off faster, but has to shift sooner. Depending upon length of race, say 1/8-th mile, normal bike may do 2 shifts while one with lower-gearing has to do 3 shifts.
So it's yo-yo effect, where lowered-gear bike gets ahead, but is then overtaken when it has to shift sooner. With the minor improvement with just 1-tooth change in front or rear, I don't think you gain enough ground to make up for lost time in shifting.
