counting official releases only, the best ones are as follows
german unremastered bluray for the first one, has the original english mono and 1:78 or 1:33 aspect ratios
uhd release for ed2 (no original audio unfortunately)
and the shoutfactory set for army of darkness
the primitive screwhead fan edit is essentially the directors cut of ed2 with some of the lines changed to the us theatrical ones, and every deleted scene crammed in where appropriate, and an altered 5.1 surround mix
