There are good aircraft, bad aircraft and mediocre aircraft, just as there are good, bad and indifferent cars. The polular perception of an aircraft or car as being iconic often belies the reality of technical design (or lack of it) and flyability (driveability). I have a soft spot for the MGB, one of which I drove daily for six years. But ..... it was out of date when it was introduced, it was hugely compromised in its choice of engine and cars like the Fiat Spyder knocked it into a cocked hat on performance and handling.
Time has allowed us to make a judgment on the Tiger Moth vs Stampe vs Jungmann. That in no way diminishes the training and ultimate sacrifice of those pilots who learned their basic flying and fighting skills in the Moth and we can all make what is ultimately a personal judgment of the virtues of the Moth, balancing design and history against flyability.
