Well, yes, I do consider the situations similar, but the GT and DB sets aren't as bad as the DBZ season sets. Apparently the DVNR and color "correction" isn't as extreme, and the 16:9 cropping has been abandoned. But, as common, they're missing the next episode previews. And apparently whoever authors current FUNimation DVDs has abandoned the tradition of using alternate angles (for things like English/Japanese title cards, etc.), so the only title cards (and logos) they use are the English ones.
Considering I'm not a huge fan of DBGT in the first place, it was a bit of a shock that the old singles were actually more complete than the season boxset (they actually included the credits and the previews), so I certainly didn't buy either of those sets. And I don't really see how the DB season sets are any better than the previous 2-disc releases from back in the day, other than the convenience and the addition of the first 13 episodes (but remember that if you have a region-free DVD player, those episodes were released in Australia)*. Since I'm all anal-retentive about getting everything as perfect as possible, I figure it'd be better if I just saved my money for the Dragon Boxes.
*Actually, would you need a region-free or other region player? Since FUNi DVDs are typically 1, 2, and 4 anyway, you could probably just import a used copy of the disc and play it just fine on a region 1 player.
