For me, this superbit editions are just marketing ploys to extract the most revenues from a DVD release. Sure, they have higher bitrates. But unless you have those large plasma screens, it's often debatable that you get any visual advantage.
AV's right, for the most part. You pretty much need a TV (of any type, not just plasma) that's 36 inches or larger to see the additional detail.
What's stranger is some of the movies they selected to make into Superbit. Fifth Element, yes. Underworld, yes. XXX, yes. Stunning visuals in these.
Panic Room, A Knight's Tale, JC's Vampires, something by Adam Sandler.. there's really no need for laser-sharp video on those.
Movies that have the eye candy (Resident Evil, the Abyss, The Mummy and I Robot would be good, or even movies with awesome backgrounds like Cliffhanger or King Arthur) make sense. "Tommy" came out like a movie shot yesterday instead of 30 years ago, but it didn't make the "story" any better...
To make just any movie into a superbit can be a waste.
As far as upgrading to Superbit, I would say no, since you'll be doing it again for Blue Ray/HDDVD some day not too far off. But if you are buying a movie for the first time that does have the visuals, it's the way to go.
