CED was superior to VHS (which was never that difficult) but inferior to LD.
Only in terms of quality, since the discs could only be used so many times before they were useless.
RCA gave the discs a life expectancy for optimum performance of 500 plays. Most VHS tapes would be in pretty poor shape by that stage. 😄

…and the majority of the films are presented in full screen/pan and scan.
Edit:
As a previous collectior of the CED format, I can testify that this edition of Raiders was in pan and scan.
As were 99% of home video releases across all formats during that era. The only films I remember watching at home in widescreen during the 80s were the TV broadcasts of Manhattan (because of Allen’s insistence) and 2001.
Out of curiosity, was Raiders ever shown in 2.35:1 by pay movie channels in the US during the 80s/90s?
Edit: interesting article from 1990 on Spielberg’s fight to get his films shown in their OAR on home video.
