I choose the Fw-190 (A versions). Good fighter throughout the war, reliable, used with success in many roles by the Luftwaffe and nice-looking aircraft. Place La-5FN/La-7 and P-38 really really close behind.
B-25 Mitchell as my favorite bomber mostly for the same things : reliability, good-looking design, effectiveness and finally for the Doolittle raid's over Tokyo. Massive respect for that !
