Nice comparison, the lower one has a deeper nose at the windscreen base and the correct flat top to the intake (not the variable intake part) which reduces the amount of fuselage seen between the intake top and canopy rail, however the upper one is more correct with the upper part of the elevon support structure beam under the fin, it is one sweeping slightly curved upper surface, the lower has a pronounced fall off toward the rear, yet the lower one is more correct on the bottom section of this structure.
I'd buy both anyway....if I hadn't just blown all my Xmas bonus on machine tools for my 'other' hobby LOL.
