A surprising 9,800 B-25s were built compared with 5,300 for the B-26. Also, the new USAF seemed to find use for the Mitchell after the war whereas the Marauder was "said" to have been scrapped right afterwards. I'm not sure whether all of the above statements are accurate (mostly wiki and aircraft fora.) From my own readings, I had the impression the B-26 found greater use as WW2 progressed. I also remember some pictures of Marauders being used during the Korean War. From stats I got the B-26 had more powerful engines (actually comparable with those for the B-17 and B-24). It was faster and carried a heavier load. The B-25 had longer range and higher ceiling. The Mitchell was definitely easier to fly, but the Marauder gave a crew bigger insurance because of its speed. I have a bias for the Mitchell because of the G-version. And it just looks better. I'm guessing an aircraft expert would give both planes a stamp of approval coming out of the assembly plant. War (and peace) exigencies just favored one over the other. What say the forumers?
