Thanks for posting the extra information. While I try to avoid the site from which you downloaded the pictures (they actively block links to CameraLabs so why should I support them by hitting their web pages?) I had a look at the originals. Given the difference in resolution there is no way, in my opinion, that you could use image processing to get the SD950 crop to look like the F50fd one. Photoshop is good but silk purses out of sow's ears it cannot do.
As to whether the SD950 image is a fair reflection of the camera's abilities, I'm afraid I have no idea. Bear in mind that the camera settings were not
identical and then there is the uncertainty over how much "in camera" processing was performed. In particular, the Powershot's lens was being worked harder at f/4 than the Fujifilm's f/5.6.
Looking at the list of cameras you are considering I would favour the G9 and might well buy one in the near future to carry with me when my 40D is not convenient. Personal needs vary, of course, but I would use that camera as the benchmark by which to judge the others. If you haven't already done so then why not check out Gordon's G9 review
