From my PoV most need some work- some good adventure sites can be picked out of them but have not run any of them in entirety and not really endeared to any of the main storylines (aka railroad) with many them. Like Dungeon mag I plunder for ideas and don't run them as is. "Princes" has been especially useful for me in this regard- some great sites- I coupled it with the Original Hommlet adventure.
However, I am playing in Curse of Stradhd with one of my regular players DMing it and really enjoying it- lots of role playing potential with that one. Lost Mines of Phandelver is a great low level sandbox that you could look at and which I Do recommend. Tales of the Yawning Portal has an update of some earlier modules (including some 1E ones) and I'd go for that over the Hoard of the Dragon Queen.
