I actually own/watch only the Rhino DVD Sets... I didn't realize how much stuff they changed/screwed up until I read about it. I guess since I never watched G1 outside the Generation 2 recuts I recorded on VHS, I didn't have much to compare to.
I'd like to get a more definitive version someday, but it's not a priority.
As for the Shout Factory Headmasters... Blackjack and I watched the TV-Nihon fan sub of Headmasters back in college, and I honestly liked that better. There was a lot less "lost in translation".
It's not like Hasbro's ports of the Energon cartoon, but there were things that were changed to fit into the current "branding" that I liked better left alone. For example, calling Fortress "Cerebros" and Battleship Maximus "Fortress Maximus" in the SF sub.
TV-Nihon also fan-subbed Masterforce, which Minerva and I recently watched. I considered snagging a SF dvd until we watched Headmasters... I think even more would be lost from Masterforce.
Also... Why is Huffer so much shorter than Brawn?
