I took this because it was free (I like free) and it contained shorter dungeons. As a dungeon master and a player I'm not fond of longer dungeons; they go on and on so that the players forget why they were here in the first place. (Longer dungeons are made because it's easier to draw and populate a dungeon than to come up with a good plot for it.) So I took the free bundle with the intention of seeing if I liked them; if I did I would buy the second bundle.

I bought the second bundle, and I'm happy with those too.
