Ochs had a musical career that spanned from 1962 or so, until his death in 1976 - but his music had gone downhill long before his death. Dylan, just 6 months younger than Ochs, had a career that began in about 1961 and continues to the present day.
Both could be terrific songwriters and performers, and both could be horrible songwriters and performers. But Dylan achieved mainstream popularity, and Ochs did not. I don't know that I'd say that one was better than the other, but it's clear that Dylan was more popular. Them's the breaks.
