Well I don't like any variations. Especially since I think Empire and Jedi are so well connected that it is a huge waste if not watched in succession (when I watch OT I even watch Empire and Jedi the same day).
As for episode order... well that's just dumb. The OT was written, designed and made in way that you start with Hope. PT is only a back-story to OT and should therefore be watched after OT.
