No doubt ImagePrint is the best option if one can justify the price.
Just for kicks I did print out a comparison between Aperture, ImageNest, and Qimage. Once again Qimage is the king. The detail and crispness of the image was noticeably better. The yellows still were not quite on par with ImageNest, but a tab bit better than Aperture. But the overall color rendition of all colors and overall print crispness was better with Qimage. Considering the options, I already have Qimage and ImageNest would be a $199 investment. Thus, I will probably stick with Qimage, but may try Fusion to get a better visualization software experience. I also need to try tweaking some Qimage settings to get the yellows more accurate. If anyone has any suggestions on tweaking settings, let me know.
