well i've seen both, and personally i like the origianl jap version. They cut out scenes for that lesson thing at the end in the dub as well as changing some key things, like Michiru's and Hakura's relationship. And in the first series they got rid of episodes, i think they tried to make it more for kids so it takes away from the storyline.

I grew up with the english version of the Sailor Moon series however now that I can keep up with the Japanese version I think it is much better

the original is in japanese!And the dub is in english!But u could get it subbed in english!

The original Japanese, when it was changed into English version, (beside it's in English) their names were changed, also was changed: The main title (originally 'Bishoujo Senshi Sailor Moon'), scenes deleted or edited and a bunch of other stupid idiotic stuff.... yeah. :'(
