Patrick Chan's SS are to die for. He has both speed, precision, and fluidity.
I'm going to disagree with you on Asada. People need to stop trying to make up excuses for her lack of speed by saying she has "control and edge and whatever". Her SS is very intricate, but she's so slow through it. Her speed actually decelerates during her SS, probably a trade-off in maintaining that quality.
Actually she always is fast at step seq considering the quality of steps. When I see a fast skater, at least in women they are slow at SS when it is a difficult one and they are fast just when they are doing an easy and usually wild unrefined step seq.
