In my view you want to avoid the 747 if at all possible. In E+ there is less legroom than the 777 but the most annoying thing about the plane is the large, bright screens for the movie. It's ok with your eyemask on, as long as it's a tight fit, but it's immensely distracting otherwise, particularly overnight. If you do go with the 747, avoid any row which is near the screens.
If the OP is serious about his program allegiance: "Don't think it matters", then the best way would definitely be non-stop on DL.
