JWST, being an Infrared telescope, is the successor to Spitzer.
Nancy Grace Roman, being an optical telescope, is the successor to Hubble.
Infrared telescopes have fundamentally worse resolution than their optical counterparts. The difference in image quality is so great that most people haven’t even heard of Spitzer compared to Hubble. Now imagine the step up from Webb to Roman.

No, sorry. Roman is a Hubble-class telescope with a wide field of view. It will do much more imaging than Hubble, but with about the same quality.
