As a matter of record, the Airfix and Dapol figures, whilst very similar, are from different tools. The most obvious difference is the base (rectangular block on Airfix, tapered mound on Dapol), but if you look at the faces and various details, they clearly vary. From the modelling point of view, the best thing is that both are moulded in styrene so can be readily adapted, rather than that flexible (polythene?) that Airfix used for most of their figure sets.
