Well, the visual quality that is available on this DVD set is second to none (out of everything that has been available so far). It is very clear. Now, these sets do contain every play in these three Super Bowls (including the false start opening kickoff of Super Bowl XXVI). The footage is the same footage as the original TV broadcasts, along with commentary by the original TV game announcers. These are the strengths of the set.
The only weakness that I perceive that this set has is that the games are still somewhat edited. Some of the action between plays is edited out. So, you may see the end of a punt play, and then it might immediately cut to the next team's quarterback taking the snap, for example. So, a lot of times things that will be missing are the players going into and out of the huddle, coming onto the field, etc. In Super Bowl 26, for example, they almost completely cut out a touchdown celebration by Gerald Riggs. I imagine that for a few people, 'cutting to the chase' in this way may be preferred, but for me, these edits create a slightly artificial feel to the games on these DVDs. This is because I consider the things that were cut out to be a part of watching a football game, such as touchdown celebrations. I think it would have been better if NFL Films had released the whole game EXACTLY as broadcast on TV, except without the commercials (of course). At any rate, NFL Films should have left that stuff in, to allow you as the viewer to decide what is important enough to want to watch; if it's on the DVD, you can always fast-forward it if you don't want to watch it. But if it's not there to begin with, then you don't even have the option of watching it. If you want the whole, uncut games, you're going to have to look elsewhere.
For having the great visual quality, and every play, but also due to the edits, I give this collection Four Stars.
