I've looked at quite a few platinum images, and my feeling is that I like silver prints better -- they seem to have more snap, and I guess I just like snap. Platinum seems to me to work best with very particular types of scenes and portraits, which are hard to specify, but I guess I would call "old timey"...pre-panchromatic film stuff, with white skies, and careful faces. They almost have the feel of 19th century steel engravings. This isn't to say that I don't like them -- they can be very beautiful when done well, but might not impress people who grew up with digital and color, rather than B&W.
