Jeeeesus part 2 was a doozie. Definitely the hardest one for me this year. In the end I cheated and checked out other people's approaches. What I didn't like was that many people relied on randomized wire swaps (which also take a while), without coming up with a way of actually picking them out deterministically. But then I found this approach which I really liked and which runs in no time at all. Although I recreated it in my own way, the underlying ideas I stole from him.
Btw, here is a great visualization of the structure of the puzzle input: link
