Good fit is the most important thing - much more so than what looks proper.
A lot of modern bikes are made with low top tubes, so a reasonable fit requires a stem with some rise, or road drops, or both - rather than the "classic" drop stem and deep bars (which were made for bikes fit for only a fistful of seatpost).
Take all of 'em out to the track, and spend some laps in each combo - do some hard efforts. You'll figure out what's best for you.
Pay close attention to your reach as well. Those are vastly different reach-wise and that can really mess with things.
My set up is a lot like the middle photo. 130 Deda stem with 3T Ergosums. But I like that as an enduro. If you're into sprinting you might like the top and bottom better as the drop in the bars suits that style better.
