Phonearena.com had the following to say about the cameras in both the Fascinate and the X:

With this class of phones, you should expect pretty good results with the camera, but once again there are a few differences. The Motorola DROID X comes with an 8MP autofocus camera, while the Samsung Fascinate “only” has a 5MP autofocus. For capturing an image, you have the traditional 2-stop shutter button on the DROID X, so you can press it half-way to focus first, and then all the way down to take the picture. But the Fascinate instead requires you to touch the screen to focus, and then to press the camera icon on the screen to take the picture. You can actually do this on-screen focus process with the DROID X as well, but we prefer using the standard 2-stop shutter button that is provided. Viewing images that we took outside, we noticed a clear difference between them. The ones from the DROID X were not only a bit sharper and clearer, but also exhibited better detail, color representation and saturation in a variety of scenes and exposures, while the Fascinate’s images looked a bit fuzzy and lacking in detail, as well as the colors not being as accurate. For inside images, the quality of both did go down, particularly in lower light levels, and this time there wasn't such a noticeable difference in terms of quality between the two handsets. Both do a good job with their LED flashes.
Doesn't matter how much better your hardware is (in theory) if it is crippled by bad software. Why do you really think it took Samsung so long to get 2.2 on the Fascinate?
