GIF is only okay-ish: No real alpha channel, only 256 colors. The later is not much relevant for grayscale images, but the former can make a difference when the page color is not white (or whatever background color the GIF was designed for).

There are only 2.5 areas where GIF has an advantage over PNG:
- Animation
- Very small icons with no transparency
- (.5) Works in ancient browsers. (GIF was created in 1987, PNG in 1996)
- There are potentially some very old ereaders that can't handle PNG
- PNG is a part of the EPUB spec though, so these devices are most likely pre-EPUB.

GIF is also part of the
ePub spec. You didn't say the opposite, but it may be worth mentioning.
The only advantage I see in GIF is that it is supported by the old Mobipocket format, whereas PNG is not... but if you are converting from ePub to Mobipocket, the converter will convert from PNG to GIF too.
