For me, it was the history data. I could check if it snowed in the last couple days in a new location and whether it melted yet. With most weather apps, the furthest back I can see is midnight, which does not even answer the question of whether there are going to be puddles/snow/slush/ice on the ground that formed since the time I went to sleep.

Yes, absolutely this. Dark Sky was very generous with their historical data, none of the others is doing that.
