If you’re OK with DVD resolution then grab em. There’s little difference for DS9 as it was only filmed for HDTV and on 4:3 digital tape. For TNG they remastered the whole series from the film originals and it’s available on 1080p Bluray for about a hundred bucks more than the DVDs. Personally i think it’s worth it for the increase in quality but it’s all personal taste.
You are indeed a wise pancake.
