Difficulty is all relative to the composition of your group. Each room has its own challenges, but each one is definitely fun!!
Blue plate, but totally depends how many people you have in your party...
They are all a challenge but I think blue plate is a little easier of the two running now
I know they don't like to compare rooms based on difficulty. Certain types of people do better on certain types of puzzles etc. Having said that, my opinion would be that the Superhero room is a little easier.
