Don't forget the aeros Queen of the Skies
Aeroed in both and both are great. The Bulldog better (proper stick, doesn't quit whilst spinning, desgined for the job, etc, etc) and easier to fly (more forgiving) from a student perspective but hey if you can find a Firefly (NOT the 160bhp) then you would have an altogether far better plane for aeros.
I am sure that many will disagree but hey that's what forums are for. I know that some will argue the repairs/upkeep are more in the Firefly but it will need less of them. You should try and fly one of these as well if you want to get a good comparison IMHO.
+6, -4 smooth and harmonized controls why wouldn't you.
