I think you're mistaken. The Dragon Boxes feature the original Japanese track, and then the Funimation English Dub (with original Japanese soundtrack) that is found on the Orange Brick releases.
[quote name='philmcfly']I got all of these as they came out 1 by 1, but what makes them so special? (I haven't done any research really).[/quote]
To date, it's the only complete, unedited release the series has gotten in North America (in its proper aspect ratio). Beyond that, they use the remastered video that was produced in Japan for their Dragon Box release back around 2003.
I think there's some debate about how accurate the colors are after the remastering process (I generally like them), especially when compared to tapes from the original broadcast, but it looks so much better than the remastering Funimation did for their Orange Bricks that it isn't even funny.

And for what it's worth, the recently started production on a Boo saga for Kai, so while the story wasn't completed during Kai's first run, it will be fairly soon.
