Thanks sgp250r for the effort, The last one has better quality. I'm not an expert in animated gifs. Maybe you should minimize the number of frames in your gif. An animated gif is just a sequence of pictures. When you use gifresizer every picture will be resized and you will loose quality.
With microsoft gif animator you can delete pictures from the queue. When you cut out every 4th frame you reduce it in size 25%. And the human eye won't see the missing frames. Hope this works for you.
