The Leica Aspherical and the APM Super Zoom are two exceptions.
The Svbony 3-8mm Zoom also has a wider field than most.
Here is a page of Zoom measurements taken in a lab:

Blue = poor image quality

Testing the 8 to 24 Orion would have been a better test, the Baader still would have won, but by a significantly less margin. I have had them side by side. There is no doubt the Baader is superior but i didnt think it was 100 bucks superior.
