Lehpron, the F-104 was indeed a Mach 2 aircraft..at 35,000 ft, where it could travel at a max speed of Mach 2.2. But, to address how fast it could go at the stated 50,000 feet, the speed of sound at 50k is 573.8 knots or 660.3 mph. Thus, the max speed of the Starfighter at 50,000 feet was about Mach 1.57.
L-188, the match-up is closer and it takes a lot for me to say this considering I'm generally a fan of naval aviation, but I'd go with the F-104 based on how widely exported it was, considering Belgium, Canada, Denmark, Germany, Greece, Italy, Japan, Jordan, the Netherlands, Norway, Spain, Taiwan and Turkey all flew the Starfighter. To my knowledge, the only export sales of the F-8 were to the French and the Filipinos.
