Just ior clarity, imho a blade is harder to hit for several reasons, I diasgree with Bob that its only forgiveness that makes the difference. A blade will generally have lower offset, offset helps square the face and get the ball airbourne. The blade will traditionally have a sharper leading edge and less bounce, plus narrower sole, these things all make it harder to sit for anyone who doesn't have a consistent swing. then there is the issue of weight distribution. They are unquestionably harder to hit for all these reasons, and then I also agree with Bob, they are also a lot less forgiving.
So if you have a very consistent swing, a neg angle of attack, enough swingspeed to generate lift, you hit from the middle all the time, you have a decent swing path and don;t need offset, and you also prefer probably a lower flight, then fine, use blades. But don't kid yourself they are no harder to use than perimeter weighted clubs, with wider sole, offset and blunter leading edge. They aren't.
