I've converted a couple of 4e adventures one short, one long and both had skill challenges in them - which I kept after changing the DC to be more in line with the lesser bonuses of 5e. I thought skill challenges in 4e were an unusual and interesting thing to DM and role-play and broke up the monotony of either combat or role-play for the players. It invested something tangible in the roleplaying part, which I guess was what I like about them. Therefore, I kind of miss them in 5e. Certainly, anytime you run a puzzle or role-play, you're basically doing a skill challenge, but I liked the way it helped keep score and keep things on track.
