I've addressed this to you, but really it's meant for anyone:
An image like this shows the utility of the Webb telescope's infrared capabilities. Hubble can't produce an image like this. But that's not because Webb has significantly better resolution- it doesn't; they're about the same- but because relatively "cold" features like Neptune's rings and clouds show up much better in the infrared portion of the spectrum. Hubble is optimized for visible and ultraviolet, with a smidge of near-infrared.
A lot of the finer structures of the universe are cold and show up better in infrared, or are behind dust that allows infrared to pass but not smaller wavelengths, and many of the oldest structures emitted visible light that has been redshifted into the infrared. The JWST should be able to "see" a lot that Hubble can't, in addition to complementing it by providing further spectra on that which it can.
Exciting times!

It’s also nice that they got Webb right the first time, instead of screwing up Hubble’s optics as bad as they did.
