I like the sleek simplicity of planes like the F-15, F-16, and F-22(pictured below)
As I've said before, I also like the F4 Phantom, even though it may not be the most sleek like my other favs. but it's big, it's bold, and it looks like it's going to kick your ass.
As for WWII, the B-25 is a real beautiful bomber
