The best performances and orchestrations are on the Original Broadway Cast Recording, but it is unfortunately a truncated recording due to only having one disc. I normally make a playlist fusing the concept album with the OBC, favoring the OBC performances when available and complete.
As for visuals, I think the original movie best captures the feel of the piece. Oddly, on stage it has always been staged professionally with gimmicks, from the 1971 Broadway production to the most recent 2012 revival. While Evita needs a concept to be dramatically satisfying because it abridges someone's entire life into 100 minutes of stage time, Jesus Christ Superstar only uses the last week of a week known religious figure as its takeoff. I think if you stage it as is, with no gimmicks or concepts, it might actually be satisfying - as the 1973 film shows (mostly) well.
