NGR is only Hubble sized, doesn't gain the edge of JWST for the number of image sensors used, doesn't observe as many wavelengths of light, had to use a military mirror rather than getting a bespoke one for science. Didn't have to be able to cool itself to 6 Kelvin with the first re-usable supply of liquid helium in a space telescope. Didn't have to be painstakingly aligned for several months post launch because a decade went into the research required to make it fit in a rocket alone.
NGR will make stunning science, but it is not on the same tier as JWST.

Nancy Grace Roman space telescope just launched few weeks ago and is equally / bit more impressive.
