In 1973 I was 31, living in San Francisco, and bought a Schwinn Super Sport. If I'd been in junior high school and had a choice between the four, it would have been the Continental (Dad worked for Schwinn for thirty years).
In retrospect, if had known then what I know now, I'd have picked the Fuji. Schwinn introduced the imported Panasonic made Le Tour in 1974, so if we were talking 1974 instead of 1973 and the LBS carried Schwinn, I'd probably have chosen an Opaque Blue Le Tour (same color as my '73 Super Sport). In '74, the Continental retailed for $134.95 and the Le Tour was $159.95, so I'd have had to sweet-talk my parents into spending the extra $25.
