#1 - not bad, but it's too blitz-like, and it only required knowledge of a couple of aspects and a program that I dislike.
#2 - solid, solid, it made many people laugh... interesting, entertaining, but nothing more....
#3 - Variability, brain-teasing:) and overall, a pleasant stage.
#4 ---
#5 - as I already said, a calculative stage, I don't see anything great in terms of heroes...
IMHO! My vote is for #3.
