Guys, remember that the Level crushing was because of the film prints from the early run. Not only did the crushing become far less pronounced as the set went on as far as it did, but because it was an artefact of the film itself, remember that this is really what the original airing prints would have looked like.
So, while the negatives at Toei would provide a better overall picture, there is something to be said for the Levels as they were presenting a look closer to how the show would have looked if you'd watched one of the TV prints when they were fresh.
Personally, I love the look of the Levels; it's a proper reproduction of what the original film looked like, the picture is sharp as a tack, every detail clear and evident (unlike Kai, which was so soft and blurry, it would often had less detail than the Dragon Boxes), and the gritty texture of the cels, the film, etc. comes through magnificently. It feels like you're watching a show perfectly preserved and rendered from its origins in the late '80s/early '90s, which is how a restoration of this material
should feel, especially for a show with a somewhat gritty, grindhouse look to it like Dragon Ball does.
You're not watching some scrubbed, disgusting, soft, faux-digital-looking mess like the HD remaster of Buffy or some of the worse-looking Disney animated classic remasters, you're watching this '80s/'90s show, as it should be seen; with all the grit of the original production on full display, not disguising it behind a shiny sheen that attempts to make it fit in with the overly-clean look of the modern run. Warts and all.
I would prefer to see it remastered from Toei's negatives, particularly since that would allow those 35mm Namek arc episodes to shine in the detail and clarity one would expect from that (Funi only has 16mm of the run of Z), but if they are using the Level masters, that will be more than acceptable.

The point of Dragon Ball is to enjoy it. Never lose sight of that.
