Given the way GIF is used nowadays the only reason it exists is it let's you put a video on the most of the places where you are only allowed to put pictures. For some weird reason many of such websites still won't let you upload an MP4 file despite they auto-convert the gifs you upload to MP4/AVC. From the technical point of view there hardly is a reason for GIF to be used at all.
