nine9six, the lower rigid fork will make your position slightly more forward and so more aero and thus it will give you less drag and make you faster. The fork itself will be more aero and faster aswell.

For my hybrid, I like the suspension fork for those occasions where I really hit the woods and go riding over stony paths and rocky riverbeds.
For hybrid bikes that are for roads only there is no need although it helps on bad roads.

Do not overestimate the negative impact of the weight and the aerodrag of a suspension fork ... I did 40+ km/h on average ... WITH a cheap and heavy suspension fork
For people who do not care about their speed and are willing to sacrifice a few percents on that to gain more comfort ... I'd say: go for the suspension fork
