I'd have to agree that the Phantom was one sweet-looking deathmachine, but for bad-ass-looking aerial death dealers, the B-1 is tops in my book.
For pure evil appearance you can't beat the B-1.
For unadulterated intent to do harm, I'd go with F-15, but the ME/BF-109 series looked the part long after they were obsolete.
For pretty, the F-101.
Raptor makes points on clean and effecient.
Finally, the A-1 stands at the head of it's very own class, utterly without competition.
Agreed. A close second is the F-14 or F-111. IMHO only.
