I own and have owned quite a few H9 ARFs (Ultra Stick 40/60, FuntanaX 100, Twist 40, Hellcat) and they are easy to build and of good quality. However, my Great Planes ARFs (Super Skybolt 60, U-CAN-DO 60, RV-4 1/4 scale) are built better. They just seem to make a more solid model. They all fly great but Great Planes, in my opinion, makes a better ARF.
