For American planes, I love the mean looks of the F14D, the A7 Corsair, and the A6 Intruder:
But alas, my heart is with Russian/Soviet Planes: The MiG-29 and SU-27(and Variants):
The super-manuverability of the Su-27/Su-37 is AMAZING!
Watch it somersault within it's own length in this video(towards end of clip):
