Paizo Dungeon is the High Mark of D&D adventure design.
Paizo Dungeon was so good, it splintered the Republic, and lead to a separatist movement.
I own Ptolus signed copy #24. Ptolus is so good, Monte Cook just raised millions of dollars by selling it again.
So you don't just expect "good", you expect the Best. If it ain't Shakespeare it is

.
Out of curiosity, are you converting the Shackled City AP to 5e? That requires effort, is that a demerit?
To me Shackled City was just OK, great for parts....but it did not engage me like Age of Worms did, or Castle Maure.
