Rhino's releases have sloppy, noticeable errors (as do the Chinese sets that copied them). Metrodome and Madman both have the added sound effects Rhino added, as far as I know [at least on the 5.1 track], and Maverick didn't get very far with their releases before going bust. There's an old comparison between Rhino and Maverick at http://kenshiroh.tripod.com/dvd/transformers_s1/ that illustrates some of them.
Shout Factory haven't fixed everything, but have tried to match to the broadcast material.
Given that there isn't a perfect set out there, and probably never will be, you may as well just get 2) and a copy of the movie. 1) apparently has some more scripts and some additional interview material, which I think is the Disc 16 contents given here;
