I made this page (posted in another thread yesterday) because I was rather underwhelmed by the .gif. I think the page shows in much better detail the difference between the telescopes' capabilities.
The reddest objects in the JWST are frequently not even present in the Hubble image, as they were redshifted into a band of light Hubble couldn't even detect. That's my favorite part about this image - those galaxies we can now see which were previously redshifted beyond our capacity to detect. They're the oldest, and receding from us the fastest.
