I don't mind sub or dub, my preference neither - closer to sub (that's my vote in poll). I do want to first watch the anime in a language I understand (English or Spanish) and then later to watch the original (as long as its not English or Spanish the originals - in this case Japanese). Many banned episodes I do have to see it with subtitles to understand whats going on in the cartoon, maybe just the first time. Like Graceful (after my post) mention while learning Japanese, its great to listen, watch, or eat too not loose what little we learn at times.
Also agree on the changes of the jokes and phrases to suit the dubbed language better.
• I find the subtitles too distracting.
• Many dubs don't match up with the voices of the characters (by lip movement).
