For anyone who has heard both, how do they compare to each other?

I've owned Legacy's Focus speakers for 14 years...but unfortunately haven't heard the Aerials. So can't comment, other than to say my Focus sound as good today as they did after 100 hours of break in 14 years ago!
However, I am getting rid of them in favor of a set of Sonus Faber Extremas (also just as old)
