I was wondering how many of the "big/long" D&D 5e (2014) have you actually played? And how many of those did you finish?
For my group it was only Tyranny of Dragons and Rime of the Frostmaiden (and the two starter sets), we finished all of them. We played a couple adventures from Yawning Portal and Ghosts of Saltmarsh, but not all of it and not as a campaign.
I have bought and read many more. I wanted to run or play Descent into Avernus, but the initial setup looked complicated and I just avoided it. I have read: Princes of the Apocalypse, Out of the Abyss, Curse of Strahd, Storm King's Thunder, Candlekeep Mysteries and Journeys through the Radiant Citadel, but never tried to run any of those.
