Kind of nitpicky, but the other version was stitched together from Twitter jpgs and has artifacts if you zoom in real close. This one is from Booru pngs and doesn't have artifacts.

For future reference, if it's JPG file, do not do any combining yourself and upload the files as is. Saving lossy format losslessly will not serve any benefit and only problems like filesize bloat. Also generally these versions are preferred to be replaced with original JPG files at that point.

With PNG files, it's still discouraged, but if it makes sense in context it's allowed.
