Just to be fair, the Trumpeter kit does have some nice features, with some of the bits being more cleanly molded (like the speed brakes.) And it may fit together just fine, but it has, as we'd say in the software field, 'bugs'. For example, the seats are too short for the scale - probably so they don't interfere with the canopy parts. The cockpit tub shows nice crisp detailing, but accuracy may suffer a bit. The engine exhausts are also clunky, surprising given how crisp some of the other parts are... so for me, the shape problems and other issues have the Wolfie come out ahead in spite of an apparently trickier construction. I think the Trumpeter kit retails for less, but with Sprue Models latest 'decal plus kit' special, I did okay - so shopping around might help.
