The Stampe is a delightful aeroplane I have a lot of time in the Gipsy powered model most probably the nicest all round light aircraft I,ve flown.It is horribly expensive to maintain and I believe all in the UK are on C of A.I have much less experience on the Bucker but have several friends who own them ,they seem very nice handling are much cheaper to maintain as most are on Permits to Fly .I have found the front cockpit of the Bucker extremely cramped and uncomfortable whereas the front cockpit of the Stampe and the Tiger are roomy enough at my girth to be acceptably comfortable.When I first started instructing on a Stampe I could wear a parachute and tighten the straps hard ,by the time I finished I couldn,t wear a chute and had to let the straps full out such is middle-aged spread and beer drinking.I found the Bucker front cockpit very restrictive.Both lovely aeroplanes though wish I couldafford to own either outright.Stampe is a real all rounder,Bucker has the edge in aerobatics.
