I bought an older version of that set that had 5 and not 6 (it didn't have the Stahlwille one, and the Witte is a different color - not sure if it's a different shape, hard to tell from the photo. I think the Wiha one is also a different color, but probably otherwise the exact same)
They are all nice. I gave most of them to friends for Christmas on a prior year. The Gedore and Wiha are probably my favorites. Wera is pretty close. I didn't like the Witte one as much because it sat awkwardly on the desk and would roll too easily (the 3 indents did not stop this well enough). But if you place it down (rather than throw it down), it's fine, and it does the business just fine.
they do make nice gifts and I kept the Wiha one myself.
