Since slide film is either for projecting or scanning nowadays, I'd say that projected it blasts even a 24mp camera away in terms of image quality on a screen, in terms of printing, since Ciba and Ilfochrome are gone, you're limited to scanning and inkjet prints. For 35mm, that's a lot of work and not really worth it, but I still shoot slides and scan with 6x7 and 4x5 and compared to our 16mp Nikon, the Nikon doesn't come close (and that's with great lenses). Something about the contrast, the hues, the's hard to beat until you drop a couple g's on digital equipment.

They are very different things, but like I said, if you plan on sharing via projection, shoot slide and blow everyone away (if 35mm). In larger sizes, it's well worth the price.
