PNG is usually produces smaller file sizes than GIF (when saved in the correct bit depth of course). PNGOUT and/or PNGCRUSH can be used reduce the file size further in many cases. There is a special setting in PNG that can prevent the gamma information being included (see http://f6design.com/journal/2006/12/01/fixing-png-gamma/ for more info including a Windows program that does this) and thus allows color consistency to be achieved among modern browsers. JPEG can alter colors too depending on the compression (and software), so don't always expect exact results when comparing the color value of a lossless image and a JPEG.
