They all have there good points and bad. The Cap harriers great but is not a good straight line plane. The Edge torque rolls are impressive but harriers are hard to master without wing rock. I go along with the Extra is the best overall plane, does most anything but none exceptional(other then the most forgiving). One thing to keep in mind is what airplane the top TOC guys are flying is the plane of the month. Extra today, Cap could be back, Edge is slipping until next year. I do agree with ibange on the Yak but until I fly one who knows. I do know that the plane you are most comfortable with is the best. For me its an Edge.
