The image from X has a slightly higher resolution, but this image from Bluesky has a much larger filesize and much less noticeable artifacts (as is the case with the recent Maggie picture, post #5175308). The only reference I have to go off of for choosing the Bluesky image is that lower-res yet uncompressed versions of images are generally preferred over higher-res but compressed versions, so please let me know if the X image is preferable after all.
