It seems to be a common misconception that JWST will give us the best angular resolution of any existing telescope. However that is not the case. JWST was designed for lower wavelengths, and due to physics reasons you get a lower angular resolution for a given reflector diameter, as compared to higher wavelengths. So even though the JWST is a larger scope, Hubble's visible wavelength photos are higher resolution than JWST's longer wavelength photos.
