The Fuji F100fd has the best IQ but doesn't seem to excel in other areas, most notably to my knowledge with colour, average macro performance , edge sharpness and not the best menu structure. Having owned an F30 I'd have to agree with the menu issue. I think too many people on here obsess with IQ without taking in to consideration other factors . Good IQ will allow for larger print sizes without noise showing but wont necessarily compensate good colour reproduction and other issues that affect exposure.
I own a Nikon S600 which is perhaps not the fastest performing with write times but has reasonably good IQ, good enough for 15" x 10" and great colour.
Depending on whether you want wide angle, IS, ultra small size etc, then I'd advise finding the right camera for you with good enough IQ for the print sizes you want. Oh, and don't forget handling. You really need to test a camera out in store to amke sure your happy with the size, feel and aesthetics.
