Another Tony vote...though, as a group, I think the Japanese had the best-looking fighter force overall of any WW2 nation! The Oscar, Tojo, Frank, Ki-100, George, and Jack have all been among my faves since I was a kid.
I believe the Oscar, Tojo, and Frank all had a straight wing leading edge, though with the pronounced dihedral, they can appear to be slightly forward-swept from some angles.
