I am so stupid-excited for Nancy Grace Roman launch just a few weeks, surprised no posts yet

it's not a competition but JWST almost pales to the state-of-the-art tech (because JWST was held up for so many years budget-wise)

28mbps downlink vs 500mbps from a MILLION MILES AWAY, 1.5TB per day download

imagine what new they will discover with it

Yes, but remember they are very different telescopes for different types of astronomy. Roman is a survey telescope with a wide field of view, designed to discover new objects, etc. JWST has a large aperture and narrow FOV to get the closest look possible at specific targets identified in advance. They will compliment each other well.

Regrettable English nit: "complement", not "compliment".
