I don't know when a guide will be made, but so far it seems as if Shirai Ryu is the most damaging, and has the most options as a result of his teleport and spears. His biggest downside tho is his slow armored wakeups, but other than that he has a great keep away game, and has pretty good mixup pressure from his low Kunais and overhead whips (which could be 3/4 screen hit confirmed into combos that end in a hard knockdown setting up his mixup game all over again like a mini vortex).
