The Fine Molds kit has the option for raised and lowered flaps while the Wingsy kit has separate alerons. The Wingsy kits wings are also a shade longer in width than the Fine Molds, Which on is correct I don’t know having limited documentation of this aircraft.
The forward cockpit fire wall/ammo bine are more finely detailed in the Fine Molds kit but the cockpit Rear Bulkhead and floor are more detailed in the Wingsy kit which also adds several PE parts. Overall the Fine Molds kit I think captures the side walls better than the Wingsy kit. The Fine Molds kit gives the interal structure to be glues to the sides of the fusalage while the Wingsy kit has the walls inluded in the cockpit tube. The Fine Molds kit may be more basic on the rear bulkhead but it includes the Oxygen bottles behind the bulkhead while the Wingsy kit does not. Overall both kits have some nice detail in the cockpit and leave others out.
