The ONLY way to tell is to put BOTH products on the car, side by side on a flat panel - then look at them. You simply cannot draw any conclusions from two separate photos - lighting conditions change CONSTANTLY.
I wish more people would do this. Nobody else will notice - the differences will be subtle. If you don't like it, polish it off and reapply your favorite goo. How long will it take you to do this to a half panel?
If more people did this, we'd have much more scientific data to back up our myriad opinions. Plus, if you leave it on for even a few days you can begind to draw conclusions about "dust rejection", or for a few washes about "longevity".
Please EVERYONE! Do side by side tests!
P.S. GuessMyName - photos DO tend to hide flaws, unless you go out of your way to photograph them instead of the reflections. But digital cameras aren't worse in any way at this. After all, even if you shot with 35mm, you had to scan the picture to get it up here on the web site - so it IS digital. In a digital camera, the camera just does the scanning in the first place.
