I have completed LoF CoT and Skull and Shackles as well as CC and many others.
CC is notable in that it doesn't give you much time to craft or do downtime. This is unusual.
LoF has significant downtime after book 1 and whilst books 2 and 3 do run on after each other it's not a race against time and you will have plenty of travelling downtime. Book 4 gives you enough time for you to do what you want although there is a plot reason for you to get a wiggle on. Books 5 and 6 don't give you much time for downtime.
CoT works best if the players are given enough time to immerse themselves in the setting. As such the AP should give you time for downtime.
S&S gives you plenty of time to set your own pace. Based on my experience of this AP I would recommend someone take Craft (Coffin) though :)...
The other two I have not got round to. Though I would advise not starting an AP until it is fully released.
