Grendel,
That version of the Ki-46 is one of the most beautiful aircraft of WWII, but I'd have to say some late war PR aircraft were better. Things like the Ar234 (range might be too short) and the Mosquito PR.Mk XVI.
The Ki-46 was definately a great PR aircraft though and a thorn in our side for most of the Pacific War.
Speaking of PR aircraft, I could see them having a real purpose in ToD. Taking the shots needed for the missions to be planned and then taking before and after shots of the results. PR Spits, Mossies, F-5s, F-8s, Ki-46s. Solo flights that when you don't return nobody knows what happened. The pilots who flew those long range, lonely missions over enemy territory were a breed apart from fighter pilots or bomber pilots.
