I'm keeping my DVDs in order to have the originals on hand if I'm ever feeling nostalgic (and also because they're worth next to nothing on the used market anyway), but I'm really impressed with the quality of the CG on the remasters. It's tastefully done and pretty faithful to the originals in terms of artistic intent. Colors and content match the originals nicely, and most of the screen caps I'm seeing could pass for CG in a feature film. They've even introduced some simulated grain so the effects shots match the live shots.

The purist in me wants the original CG recreated as well, but rather than re-render CG to match the originals and include them with the remastered film elements, which would be an odd juxtaposition, I'd prefer they create new SD masters from the original 480i broadcast tapes and offer them as downloads or bonus content for people who buy the Blu-rays. The existing DVDs are a travesty and a proper SD release would preserve the original broadcasts in their original quality.

I say this expecting comparisons to the OT "bonus content" theatrical cuts, but this situation is different because TNG was originally crafted and mastered with the intention of showing it on TV in 480i. A clean SD release would be in keeping with preservation needs in my opinion.
