My impression is coverage, skyscanner appears to have pricing from a huge number of sites/resellers which is important because in my experience the same flights from different sites can have significant discounts over each other.

I've tried using other sites before and while the UI on hipmunk is nice my experience was that skyscanner normally found options which were cheaper or didn't show up at all.

But I live in the UK and typically I'm booking long haul to Asia, I don't know if the situation is different elsewhere in the world or if perhaps skyscanner is concentrating on the UK market as its home market to an extent.
