I wandered for a long time through many outlines for my prequel rewrites, from Flash Gordon-y serial shlock to dark psychological thriller, and even explored the idea of creating an entirely new cast of characters for the prequels and having the OT characters sidelined or eliminated. I think I was searching for the 'best' prequel story possible, but it's impossible to know if you have the 'best' story out of endless possibilities. For some people, the best prequel story would focus on Anakin as the protagonist, for others, Obi-wan would be the natural choice, and for still others, neither should make substantial appearance.

I think that the ability for the OT to unleash such power of imagination is its greatest strength, and any definitive prequel story would only diminish this ability by replacing wonder with definition and dogma, much as the EU and the Lucas Prequels have done to the story. In this way the OT is a work of art in that it is highly interpretive, with a single statement or turn of phrase in the films creating enormous realms of possibility.

So in answer to your question, I don't think people will ever come together to decide upon a single best prequel story, at least not while the story is still centered around characters from the OT, for the simple reason that everyone has a different interpretation of those characters. Same with the Star Wars galaxy itself. Everyone has some idea of what happened in the Clone Wars, and it's all somewhat different to each person. Perhaps having the PT take place much further in the past, and creating a story that is essentially a new take on Star Wars, not relying on anything in the OT, would allow it to stand alone and generate its own universe of interpretations and possibilities. When someone does that, with a cast of characters that is as interesting and timeless as the ones in the OT, then I'll be on board.
