Galio's E speed buff doesn't last for 5 seconds, the directional wind thing does. Galio's E is limited by the fact Galio stops to cast it and only allies in the thin directional line get the benefit whereas Sivir's ult has no such limitations, animation or positioning-wise.

Also, one is an ad carry and one is a utility mage/tank who sacrifices things like damage and mobility for his speed boost. Sivir was giving out that strong team utility while also doing crazy amounts of damage throughout the game. You have to factor in the whole package when it comes to things like this, not just compare two skills' numbers.
