If you want a better 3D performer, the Edge usually is a better plane and can fly sequences well. The Extra is a better sequence plane and can do 3D well. So it depends on what type of flying you want to do. Between the two you mention, I'd go with the A/W as it is a little larger overall (105" vs 97" )

I'm sure you'll be happy with either plane. If cost is a factor, the H9 can be a great performer at a lower cost. Because it's smaller, you can go with a ZDZ80 and get great perfomance. The Edge usually needs a 100cc (twin) not only for the large size (drag, weight), but because it also needs the nose weight (the plane was originally designed around the 3W85B2 (7 lbs) ).
